As a Ford guy I’m pretty happy seeing Mopar stuff on the channel, it’s different from the norm. I’d really like to see a set of Kaase SR-71’s for a BBF make their way through there for a review. They seem to be the new darlings now. Even the older P-51’s would be cool to see.
Ok this is my $.02 , Mopars are very different from others , , Rod ratio is a longer above 1.8 on a stock 440 & still above 1.7 on a 512 stroked build , so the piston moves faster in the middle stroke & stops longer at both ends of the stroke this increases velocity in the head & continues to fill the cylinder at the bottom with the piston stopped & allows longer combustion time as it initially moves away from TDC slower , this has a huge effect on the effectiveness of the ports & requires very different cam grinds ! I have never struggled to make great power with "small" Mopar heads
Good review Eric. I thought the heads flowed pretty good considering the cross sectional area. I have used several sets of 270s and had real good results. I can't wait till you test a set of 270s. Thanks again. Take care, Ed.
Thanks for the video, I have these on a 440! I think most of the criticism is due to Trick Flow needing these to be bolt ons. Confined by the architecture
B-1s ported are beautiful things!...easy 8 sec ride when done properly. I run 270 TF on my #2 back up 496...650HP on a 10.6 engine is very easy. Also keep in mind most 500 ci mopars don't need to be spun past 6200, to make so decent big #s on pump gas. The B1 shines at 7k and up.
how does the D-8 gen2 hemi iron 2020-casting date code street dealership's-Dodge heads ( new combo in the works is 4.3X4.5" stroke so Eric's testing is 👌as it's the same as mine or super close as i opted not to run for stupidity big of 4.5 bore's as it's known for blowing gasket's and im looking for higher run time TBO's and it's boosted ) stack up compared to the iron 906 ( my old combo was a 1968-69-70 sorry the owner before me mixup years 4.3 bore aka G-383 ) replacement's as Eric said are better
All of these (save for the Brodix) are standard port. Serious Mopar guys run the Max Wedge sized port. That's what the Trickflow 270's are. The 240's with a 505" shortblock make awesome torque and are great fun in a street car. Easy engine to build as no major mods or grinding for 4.25 stroke required.
@@danielslocum7169 I was also curious about the Victor's. As I understand, there is a version that is smaller than Max Wedge, but I suspect the port opening cross section is bigger than stock...
@@metallicareload68 i could be wrong,but i thought the victors are all max wedge ports. i know there is a std size victor intake and a max sized super victor intake. you are correct about the 505 using small ports on the street;torque is absolutely brutal! im building my second 505 for a friend right now and a 3rd is planned for another friend.
Chrysler's race engine was the Hemi. 440s were a passenger car engine. Ford 427 highrise/tunnel port, SOHC and Boss 429 did battle with Chrysler 426 Hemi's untill all these engines were outlawed. That's when Chevrolet began to shine.
I like seeing all the different engines and their designs. Heads design differences are pretty amazing between different makers even for the same engine family.
I know I am a Mopar nerd, but I have similar money in my turbo small block as any other platform. I am stoked that TFS at least has made some decent heads for Mopars! Thanks for doing the review!!
To be fair, Mopar designed the B/RB engines to be smooth and torquey for stock, street driven cars. The 270 Trick Flow is based on the Max Wedge engines of the early 60's. The engineers understood that the standard designed heads just weren't up to the task and set about to design a better head. But they finally decided to make a radical departure and of course they came up with the '64 Race Hemi and those heads flow pretty respectably for a big block head designed almost 60 years ago. From tests I've seen on stock 426 Hemi heads, 320 to 330 cfm max flow is about their limit. And of course they were ported from there.
Those flow numbers would be really good for a 240cc sbc head. I know the relatively big valves help out. Compared to something like a 240cc aluminum cleveland head with similar valve sizes these heads still hold their own.
I built an Indy 440-1 heads (as cast mild clean up and VG) 440 (stock stroke x .030 over bore) back 30 years ago. Customer didn't have the budget for a roller cam setup so these numbers are off the shelf flat tappet and RPM limited by spring pressure. It made 730hp @ 7400RPM. It had not reached peaked HP when valve float stopped it @ 7400. And yea, it was weak on torque @ around 550lbs/ft due to the camshaft compromise. He put it in a very heavy 70's Cuda @ 3700+lbs w/ auto trans. It ran some 10.20's, with 10.40-10.50 range being normal. Those heads flowed around 375cfm if I remember correctly. So yea, there are much better heads available. The heads I used had bigger max wedge size intakes and raised exhaust ports. Any version of the B-1 heads would kill the Indy heads I used for HP potential.
Indy heads can flow 400+ with standard valve, but I know guys that make over 900hp on big bore setups with 440-1 heads that were seriously worked with chamber mods. B1 stuff is very good but more work and money needs to be put in them. Nice numbers on 440, would work great in some a body.
Thanks for the intensely detailed analysis of the Big Block Mopar Head. 20 years ago, I purchased the Edelbrock RPM head. No TrickFlow Heads available back then. My current heads are waaaay better than stock, but now ya have me lusting for the 270 heads...
Also have the performer rpm heads. Built in 2002, not a ton of options then. Seeing some reviews on them compared to current heads, I'm debating switching up the heads too. 270 might be best for my build, bored and stroked pushing 496 c.i. now, big lobey cam etc...
Yes. Serious mopar guys are running B1 or Indy heads. The trick flow are best for low deck 400 strokes kits. The weight of the pistons on mopar big blocks restrict rpm. But before you count them out. A 440 stroker and stock cast heads / on bias ply tires are running faster them the s10! That's also with cast intake and manifolds!
nice overlay I have the 440 trick flows on my street engine and have used them on customers engines very easy to make a std stroke 440 with small solid roller 640hp on pump. I also had the Stage VI heads that I modified for racing way back when... They were a good head flowed 352cfm with a 246cc runner . I have also done a LOT of B1 testing due to the bracket I was running in and they really are a solid head to work with. i spent months every day developing that head. I am surprised my bench still works lol. be intresting to see how it goes for you. also as a side note the indy 440-1 head I have had flow to 390cfm only problem was trying to find a set that the seats were put in square.
Thank you Eric for taking a look at the Trick Flow 240 … you seem to be saying that it is probably the best out of the box bolt on head for the guy that wants to keep standard manifolds. For the Stroker Guys (505, 512 etc) maybe (even on the street) the TF 270 would make more sense. I look forward to hearing your thoughts if TF would loan you a head?
Nice vid. Maybe you could do a video on chambers? I was reading some comments by Darin Morgan about port recovery and how that affects the power. But it seem like a tricky subject that many arent aware of. So an video explaining it and what a good chamber looks like. Darin mentioned the SB2 heads as an example of having good recovery. Just an idea.
This head would work really well on a stock 3.38 stroke 400 "B" block. . The 270 version is limited as it requires "Max Wedge" intake and exhaust components. Power Nation made 630 HP with these heads on a 512 stroked 440 carburated.
hehe, Trick flow should made 240 cc for small block mopars. Be great for 383 Magnum or the 400 with stock stroke, though 600 hp was had over at Nicksgarge
@@thomasward4505 well he did dial in the amount of Oil in pans. he did not have a racing vaccum pump though .so withought another Dyno test posted We dont know for sure
Thanks Eric, good info. Wait till you see a 440 victor with a 2.25 valve and MW port opening 😮 I'm eager to see what you get out of those B1s do after you port them tho 👍🏻 Keep us posted.
Great video and thanks! The Engine Masters show compared stock iron, Source, Edelbrock, TF240’s and 270’s (270 has slightly raised port and Max wedge size entrance) on a mild 440. The 270’s didn’t hurt the low end at all and then walked away from the 240’s by 20 or 30 horse iirc.
Realistically, this oughta be a excellent head for the street, especially, for the leaps over the stock heads, as you pointed out. I’d expect excellent drivability from this head, for a great seat of the pants sensation, over max performance heads, depending on price. I see potential for the with 400cid B-block apps, especially for the over square bore - stroke.
These heads are way ahead of what we used to have. Still Trick Flow should have designed them like the 11R or the TW R head. That Brodix head looks wicked.
Thank you for doing this. I'll be paying attention. I put a hole in a cylinder of my 543 and also ruined a 440 Source CNC head. I need a new top end. I'd really be interested in seeing some flow numbers of the TF 270's, the Indy 440-1 345's (etc), the Brodix's and anything else in this range. I'm working with some high altitude, low PSIA (12.2-ish) too, so I need air flow!
The best option would be Indy or B1 heads bought bare and worked by someone good. I love Indy stuff but what you get from them is far from being ready to bolt on. Trick Flow is best in that fashion but 270 head is not going to be enough. They cn be ported further but buing cnc ported stuff to have it hand ported more does not make much sense.
Realistically, if you can keep the oil in it, a 440 is just big / properly sized small block. Big bore, short stroke (good rod ratio) - with shaft mounted rockers
As a Ford guy, I don’t have much room to wiggle with when I say, I thought a big block head would’ve flowed a lot more. 440 magnums back in the late Stone Age had quite a reputation.
Have those heads on a 400. The size is pretty healthy for that size for about 7000 rpm. The problem with BB mopar heads is the factory port opening, it's only about the same size as in a SB chevy. They had a bigger port used in early 60's, Max Wedge, and there are heads for that size (like the 270cc TF), but the intake availability is very limited, and it's still not very big for a 500 cu in or more. You keep telling about the awful chamber of the BBM aftermarket heads, I believe it's partially because they want that you can use any (domed) pistons meant for the factory heads with them. Factory valve placement (not optimal) and angle pretty much dictates that. The B1's are much less compromised, but of course no factory parts can be used with them. There are others too, Indy Cylinder heads have a good selections of heads from mild to wild to full fill almost all needs. I personally have FBS heads on my big block. They are closer to B1's but with even higher and smaller ports, and flow pretty well for the size.
Tonnes of guys are over 700 with these heads. The smallest I've seen is Andy Finkbiener's 470. Off the top of my its a 400 with a 3.91 crank, h beams and flat tops. 260ish @50 solid roller, tf240 heads, M1 sp and a 950 dom, with 2" headers. He documented the build and dyno time on one of the forums.
Man this is sad that the big block Mopar aren't as good as I guess they need to be. Basically a bigger sbc head I guess. But that's cool you got to share these Mopar heads I can't wait to see more of everything
This head would actually be better on the Mopar B-block 400 (than on the RB-block 440). The shorter stroke 400 evolved out of the old 383 in the low compression 1970's. But is a strong block worthy of custom building.
I have a set of gen 3 hemi Edelbrock heads I'm running. Gonna refresh my motor. What would you charge to port and flow my heads? These heads claim there is extra 200 thousands for porting.
I just did a 440 with those heads. Nos trw .030 over pistons, 10:1, thick rings, comp hyd roller, single plane, it made 510hp, 540tq, 91 octane, it wouldn't rev past 5800 due to the hyd rollers
lets be honest what are all the top fuel cars in drag racing running essentially gen 2 hemi. And all the 481x cars that dominate still based on the the hemi architecture with a loosely based bb chevy wedge head.
I would like to know if the procomp speedmaster head flow 370 to 380 cfm with a 750to 800 lift cam after you port it on a 4.350 bore plate standard port cnc flowed or max wedge port. Enjoy your porting videos. Your the only one showing any real port work for big block mopars.
Love your stuff. I am a big block mopar owner and I need stock appearance . So which would flow more stock head fully ported or a cnc 440 source head and if stock which casting. Thanks
The 440 Source has multiple improvements over the factory castings not to mention the Huge weight savings. I've done alot of work with 452's & 706 head's & with much less work the 440 Source head outflows them. We have lost Many of the MOPAR specialists in the last few year's on porting. Even INDY doesn't have anyone anymore. It's sad but not too surprised as it's a dying art
@@TheDynotuner Do you know how much is it safe to deck 346 heads? Someone unfortunately put them on my 1967 383 with 4B instead of machining new seats on the original close deck 516 heads. I am in Europe so shipping new heads is expensive (20% tax and 500USD shipping on top) and I also have friend with machine shop so new valve seats, valve guides for edelbrock rpm valves, spring seats and decking are possible. On other hand neither of us ever worked on Mopar heads so proper porting is out of question. Only basic port clean up and a lot of research ... a lot. Or I could buy 440source heads and set of US made keepers, check and clean everything , paint it blue and call it a day. Heard there maybe be oil flow issue to rocker shaft at sustained high rpm. We tend to run 90mph on the highway around here so there is definitely more strain on the motor and making it bulletproof would be also a goal. Car is a street deal with slightly upgraded suspension and steering to handle our narrow roads and somewhat more spirited driving. Shame I cannot put something like these TF240 heads on it. Any advice is greatly appreciated. Thanks.
Wath dou you tink abaut Chrysler MP 425 Alu Heads (Wedge)???? This are CNC Ported.With May Roller Hyd Cam Lift 0.585 (Flows 310 Cfm.) Have sixpacks modifaid even Nice ported.No Chok i dont draive in Winter🤣.
You described the Mopar guy to a T. I had a "Rumble Bee" owner get pissy with me, because I helped a kid he worked with, do a cam and springs, and just some minor tweaking with HPTuners on a GM WT2500 4x4 beater and it spanked his precious yellow pickup, and sounded a lot meaner.
You get what you paid for with trick flows, it does suck the aftermarket support is limited and seeing all the numbers that Ford and Chevy are hitting with flow is like what the hell but the Mopar has its own benefits
I think too much emphasis is put on chamber design. I always hear They are more Efficient but no one ever explains what they are more efficient at? Fuel mileage? Clean burn? HP? TQ? I call BS. Until someone spells it out I guess us dummy’s will never know. I see BBM make great numbers with the low flo heads all the time. It is kore than just flo Numbers that make good power. Again Mopar has some other internal engine designs that help the entire package. Bigger lifter bores and as mentioned above the piston speed at mid stroke. I’ll always be a Mopar guy cause they are what I know and prefer. I drive a 4x4 pickup and there isn’t another truck around that can beat the old dodge trucks when it comes to tough truck and off road fun.
Eric you might care to look at this video from Sampson’s Speed Shop. The 440 on the dyno is using TF270’s. At minute 10:10 they say that Pete is working on a six pack intake for the Trick Flow 270 heads. ruclips.net/video/8gQTh4NdECk/видео.html
Simpson Speed shop's engine dyno guy made 780+hp, 700+fl;lbs with Trick Flow 270's on a 493 big block Mopar. Engine Power always build weak ass Mopars. They're a chevy show. They got embarrassed when the big block ford stroker out powered their beloved big block chevy. Even though the Ford was smaller.
Let's not get confused. The Gen II Hemi design owns Top Fuel the fastest class in drag racing. It is a mopar design, not Chevy or Ford. With that, flame on with the lowly wedge comments.
As a Ford guy I’m pretty happy seeing Mopar stuff on the channel, it’s different from the norm. I’d really like to see a set of Kaase SR-71’s for a BBF make their way through there for a review. They seem to be the new darlings now. Even the older P-51’s would be cool to see.
Kasse is a wizard. And I'm the mopar die hard he's making fun of.
I’m a ford fan but voted for the 440 because Variety is the spice of life

Those heads flowed around 375cfm if I remember correctly. So yea, there are much better heads available. The heads I used had bigger max wedge size intakes and raised exhaust ports. Any version of the B-1 heads would kill the Indy heads I used for HP potential.
Indy heads can flow 400+ with standard valve, but I know guys that make over 900hp on big bore setups with 440-1 heads that were seriously worked with chamber mods. B1 stuff is very good but more work and money needs to be put in them. Nice numbers on 440, would work great in some a body.
Must of had twin turbos to get those numbers for a 30 over 440
Thank you from a Mopar guy!

Yes. Serious mopar guys are running B1 or Indy heads. The trick flow are best for low deck 400 strokes kits. The weight of the pistons on mopar big blocks restrict rpm. But before you count them out. A 440 stroker and stock cast heads / on bias ply tires are running faster them the s10! That's also with cast intake and manifolds!
I would have liked to see the Edelbrock RPM heads included in the comparison.

Right on
I'd love to see the 270 Max Wedge heads . A guy went from 10.40s to 10.0s out of the box . That much better than worked MW heads .
These heads are way ahead of what we used to have. Still Trick Flow should have designed them like the 11R or the TW R head. That Brodix head looks wicked.
It's an intermediate head! They always said it was.

My 471 engine made 692 at 5900 and 667 at 4800 with 2- 850s on a ported tunnel ram and a sorta small 264-268 @.050 sft. And 12.9 compression
Realistically, if you can keep the oil in it, a 440 is just big / properly sized small block. Big bore, short stroke (good rod ratio) - with shaft mounted rockers
As a Ford guy, I don’t have much room to wiggle with when I say, I thought a big block head would’ve flowed a lot more. 440 magnums back in the late Stone Age had quite a reputation.
Have those heads on a 400. The size is pretty healthy for that size for about 7000 rpm. The problem with BB mopar heads is the factory port opening, it's only about the same size as in a SB chevy.
They had a bigger port used in early 60's, Max Wedge, and there are heads for that size (like the 270cc TF), but the intake availability is very limited, and it's still not very big for a 500 cu in or more.
You keep telling about the awful chamber of the BBM aftermarket heads, I believe it's partially because they want that you can use any (domed) pistons meant for the factory heads with them. Factory valve placement (not optimal) and angle pretty much dictates that.
The B1's are much less compromised, but of course no factory parts can be used with them. There are others too, Indy Cylinder heads have a good selections of heads from mild to wild to full fill almost all needs.
I personally have FBS heads on my big block. They are closer to B1's but with even higher and smaller ports, and flow pretty well for the size.
So what your saying is these would be great on the 383 Mopar?
Not a mopar guy just wanted to see what that head would flow
270 as the same ex port intake is open to maxwege same head or same casting
Ha ha ha those heads make 700hp out of the box.
Do you run these one your Mopar? What else are you spinning in there if we might ask?
Tonnes of guys are over 700 with these heads.
The smallest I've seen is Andy Finkbiener's 470.
Off the top of my its a 400 with a 3.91 crank, h beams and flat tops.
260ish @50 solid roller, tf240 heads, M1 sp and a 950 dom, with 2" headers.
He documented the build and dyno time on one of the forums.
Man this is sad that the big block Mopar aren't as good as I guess they need to be. Basically a bigger sbc head I guess. But that's cool you got to share these Mopar heads I can't wait to see more of everything
My little 440, TF, Dana equipped Duster wasn't the fastest. But always consistently ran the number all race long.
Have you ever flowed an Indy 440-1 345cc head?
The B 1's not too shabby there. Those Brodex heads look like they could help churn out 750/850 HP. Can they?
Like your videos
The 240 has the ability to save money by running a stock type rocker shaft/location
The good ting is bolt right on only longer pushrod
This head would actually be better on the Mopar B-block 400 (than on the RB-block 440). The shorter stroke 400 evolved out of the old 383 in the low compression 1970's. But is a strong block worthy of custom building.
You should reference the MacFarlane formula and port velocity when talking about the cross section area.
I have a set of gen 3 hemi Edelbrock heads I'm running. Gonna refresh my motor. What would you charge to port and flow my heads? These heads claim there is extra 200 thousands for porting.
I have a friend thinking about getting the 270 heads,if he ordered them from you would you flow them?? Maybe port if he desides to go that far?
How well would it work on a stick stroke 383?
I just did a 440 with those heads. Nos trw .030 over pistons, 10:1, thick rings, comp hyd roller, single plane, it made 510hp, 540tq, 91 octane, it wouldn't rev past 5800 due to the hyd rollers
I would expect much more power. Are those pistons very heavy? Something's not right with that combo.
Even Trick flows Max wedge 270 is pretty small compared to other big port bbm heads, you should see a set on indy heads
lets be honest what are all the top fuel cars in drag racing running essentially gen 2 hemi. And all the 481x cars that dominate still based on the the hemi architecture with a loosely based bb chevy wedge head.
Need to see the 270. I've seen 270s on the Dyno put down almost 800 hp. 500 ci tho....
Thank you
I would like to know if the procomp speedmaster head flow 370 to 380 cfm with a 750to 800 lift cam after you port it on a 4.350 bore plate standard port cnc flowed or max wedge port. Enjoy your porting videos. Your the only one showing any real port work for big block mopars.
Tanks I just buy one set just bolted on my 440
We to get this "270" head ASAP !!!!!
Love your stuff. I am a big block mopar owner and I need stock appearance . So which would flow more stock head fully ported or a cnc 440 source head and if stock which casting. Thanks
I don’t port cast iron so I don’t know on that. I would do the 440 source though if it were me.
@@WeingartnerRacing would get stock 440 source and Port it or buy there cnc ported one
The 440 Source has multiple improvements over the factory castings not to mention the Huge weight savings. I've done alot of work with 452's & 706 head's & with much less work the 440 Source head outflows them. We have lost Many of the MOPAR specialists in the last few year's on porting. Even INDY doesn't have anyone anymore. It's sad but not too surprised as it's a dying art
@@TheDynotuner Do you know how much is it safe to deck 346 heads? Someone unfortunately put them on my 1967 383 with 4B instead of machining new seats on the original close deck 516 heads.
I am in Europe so shipping new heads is expensive (20% tax and 500USD shipping on top) and I also have friend with machine shop so new valve seats, valve guides for edelbrock rpm valves, spring seats and decking are possible. On other hand neither of us ever worked on Mopar heads so proper porting is out of question. Only basic port clean up and a lot of research ... a lot.
Or I could buy 440source heads and set of US made keepers, check and clean everything , paint it blue and call it a day. Heard there maybe be oil flow issue to rocker shaft at sustained high rpm. We tend to run 90mph on the highway around here so there is definitely more strain on the motor and making it bulletproof would be also a goal. Car is a street deal with slightly upgraded suspension and steering to handle our narrow roads and somewhat more spirited driving. Shame I cannot put something like these TF240 heads on it.
Any advice is greatly appreciated. Thanks.
👍💪
Whatever happened to Indy Heads? Still available?
Mopar is all about torque
Hello Eric, I have a question for you: why no back cuts on exhaust valves?
helps fight reversion
Why don't they make an adaptable hemi head?
I'd like to see before and after flow numbers for that B1.
I probably will not show the before numbers because it has no valve job done on it.
Try to get the trick flow heads that are max wedge port if you can thanx
Wath dou you tink abaut Chrysler MP 425 Alu Heads (Wedge)???? This are CNC Ported.With May Roller Hyd Cam Lift 0.585 (Flows 310 Cfm.) Have sixpacks modifaid even Nice ported.No Chok i dont draive in Winter🤣.
Well I'm not interested in these 240's anything bigger? These heads are fine for 550/600 HP. Is there something better?
You described the Mopar guy to a T. I had a "Rumble Bee" owner get pissy with me, because I helped a kid he worked with, do a cam and springs, and just some minor tweaking with HPTuners on a GM WT2500 4x4 beater and it spanked his precious yellow pickup, and sounded a lot meaner.
You get what you paid for with trick flows, it does suck the aftermarket support is limited and seeing all the numbers that Ford and Chevy are hitting with flow is like what the hell but the Mopar has its own benefits
Do you have 426 hemi plate? I want my dart heads flowed
Nope sorry
Hello I want to know do you think speedmaster 440 heads can flow 370cfm
I don’t know I don’t work on speedmaster heads so I can’t say.
Now do a Predator head.
why bagging on the chamber ? that's pretty much the latest heart chamber GM and ford are using in their production stuff.
It’s close like Pepsi is to coke.
I think too much emphasis is put on chamber design. I always hear
They are more
Efficient but no one ever explains what they are more efficient at? Fuel mileage? Clean burn? HP? TQ? I call BS. Until someone spells it out I guess us dummy’s will never know. I see BBM make great numbers with the low flo heads all the time. It is kore than just flo
Numbers that make good power. Again Mopar has some other internal engine designs that help the entire package. Bigger lifter bores and as mentioned above the piston speed at mid stroke. I’ll always be a Mopar guy cause they are what I know and prefer. I drive a 4x4 pickup and there isn’t another truck around that can beat the old dodge trucks when it comes to tough truck and off road fun.
You compare maxwege port to stock port
Sadly the published exhaust flow numbers for the 270cc head are exactly the same as the 240cc. 😢
Eric you might care to look at this video from Sampson’s Speed Shop. The 440 on the dyno is using TF270’s. At minute 10:10 they say that Pete is working on a six pack intake for the Trick Flow 270 heads. ruclips.net/video/8gQTh4NdECk/видео.html
Simpsons
I’ve seen the original b1 head flow 426 cfm at .800 and that is an inferior head to the b1 mc head
Simpson Speed shop's engine dyno guy made 780+hp, 700+fl;lbs with Trick Flow 270's on a 493 big block Mopar. Engine Power always build weak ass Mopars. They're a chevy show. They got embarrassed when the big block ford stroker out powered their beloved big block chevy. Even though the Ford was smaller.
Why not an AMC V8 head? They have the same bore centers. They’re not that far from a440.
Even less than mopar customers.
Surprising that 440 source head is that bad. They flow less than the TFS small block mopar heads
Let's not get confused. The Gen II Hemi design owns Top Fuel the fastest class in drag racing. It is a mopar design, not Chevy or Ford. With that, flame on with the lowly wedge comments.
Sweet video!!! Please check out my 1968 Barracuda fastback powered by a rowdy 512 stroker backed by an A833 4 speed manual. I think you'll approve. 👌
A lot better oiling witb 240’s
