@@richardholdener1727 Your 326.7 rounds up to the 327, at the same time the 331.6 did not round up to a 332. The worst that I know of, the 350 Pontiac measures 354 cubic inches. Hope this helps what I was getting at. Have a great day and I enjoy your videos.
Thinking about building a 351w with rpm airgap afr 205 heads and a procharger, with a torque cam . Will be going in a 84 bronco ought to be fun dont know what hp i can expect ought to be fun though.
Put 180 degree headers on a sbf and see how much hp is gained. On a stock, mild or highly modified engine. I think the European sound would be neat on a dune buggy or something.
Contrary to your disappointment in the video, I think the 427 was very strong! My personal rule of thumb for a strong NA engine is 1.4 lb-ft per cu in at the torque peak and 1.25 lb-ft per cu in at the horsepower peak. Your 427, with very good parts in it except for the rockers, was well over those numbers by my calculations. By comparison, the 363 NA numbers were well short at about 1.3 and 1.2 respectively. It didn’t have 13:1 compression so maybe that’s understandable. It’s all good info, as we’ve come to rely on you to provide. Thanks!
On combo #4, the 418 Windsor, I think the 1 3/4 inch headers are too small. I would have liked to see a 1 7/8 inch primary because it's not to going to overhang the port all the way around like the smaller flange/tube does....which is a bottleneck right at the head.
Five minutes into the video and so far I hear aftermarket block. I'm not a mechanic. I'm a Street racer from way back. And with a aftermarket block, should be able to make over 700 horses and not have to worry about the block
Richard, was the 427 expectation that better shaft rockers would allow the engine to make more power by running higher RPMs, or were the rockers being used already cavitating and stealing power that a stiffer set-up would have been able to accommodate? Was the intent to give it more cam? Just trying to understand how it would make more power. I am looking at an LS version of this approach and was thinking 750hp was about the limit of what could be expected, and to be honest would be plenty nuff. Probably targeting a usable 8,000-8,500 rpm redline. Just tying to get as many vantage points I can before dropping coin on that kind of build.
That would be a good one with the OEM 2bl closed camber heads along with some of the down under aluminum heads from pro comp to the top dollar heads and also p-38 heads offered by Jon kassie that would be very informative and I'm sure help a lot of guys decide on what set up would be best for them !!!
Bobby Rosetta I’m at the point where I’m selecting cam and cylinder heads. I’ve found a pair of closed 4V heads on eBay in the 1.3k region. I’m be also found a guy who has genuine Aussie closed heads cast by ford in Australia would still need valves and everything. But I’ve heard they’re a good middle ground between the 2V and 4V ones. So I’m kinda debating which way to go. I have some time at least while the car is getting painted to decide.
Question??? I notice on the smaller displacements that the torque and HP numbers are pretty close in proximity, which I've been told thats signs of a good build. However, on the larger ones the numbers are a bit further apart. Is there a reason for that?

Is it true a 1992 ford with afr heads makes 400 horsepower all my friends are telling me that this is true but I think that a cam and other things might need to be involved and this was in a Lincoln 1992 Lincoln
@@richardholdener1727 thank you.I also told them I need to fly cut the pistons to work with the afr heads.or do you think I'm wrong? I really love the videos you share.
How in the world did that 331 make 448 with an xe274? Those heads must have been ported to perfection. You see I am trying to guesstimate my power. I am running a 331 with 9.6 cr and afr 185 heads with a performer rpm and comp 281hr cam with 1.7 ratio rockers. I figured it made 420 hp. So for my 388 build i bumped up my cam to an edelbrock 2281 ( 299 duration) in hopes of making 520 hp...your 408 stroker in the previous video only made 534 which made me think that no way my 388 would make 520, but maybe those afr 185 heads flow better than the trickflows on the 408.
@@richardholdener1727 They made some pretty good kits. I live here in NM. I bought one of their 03-04 twin kits on a forum a few years back and thought I got a good deal until it showed up. The guy shorted me the intercooler and some charge piping. I wish they were still in business. Unfortunately it's pretty hard to track down the pieces I need.
@@richardholdener1727 I can't find the article. The website is down. I took a screenshot of it years ago but that's on an old phone. If I remember correctly it basically said the LS has many Ford attributes such as bore spacing, head bolt pattern, deep skirts, cross bolted mains, firing order, etc..... because it was designed by a Ford guy. I think it was Robert Yates that had a hand in the head design specifically. Supposedly the LS head bolts onto a sbf but it needs some Frankenstein parts to make it jive.
Not a big fan of Ford either... But at least your showing guys ford combos that a make big power without going LS all the time... Keep ford with Ford... Can't wait for that 455 Buick again🗣️🗣️🗣️
Lol, low compression? How bout 13:1 with twin precision turbos, 22psi boost, carburated running meth, around 1300hp to 1500hp. I dont get why guys still build engines that run below 9:1 compression ratio. If you have proper fuel available from the pump, or the car wont be used as a daily, give it compression. Id like to hear your opinion Richard. Im thinking about playing with high compression and some boost, but will be on a 4 banger. Highest octane here in my country is 95 unleaded pump gas. We dont have many options when it comes to v8 engines. A run of the mill old school small block engine will cost you more than buying a 1uz and swopping it into the car, including everything you would need to get the auto tranny shifting and tuning. Hence every 2nd pickup here runs a toyota 1uz.
That's 427 needed different heads. Y'all threw up money on some garbage heads don't matter how much the flow bench test are. Afr 225 or some kasse p38, trick flow r or high port. If I did n new motor would be aluminum 363 dart block with some AFR 225 outlaws and 1 turbo for mild street motor of 800hp/torque or race gas for 1000hp.

the 427 made 1.75 hp per cubic inch-the 363 made 1.56 hp per inch

@@richardholdener1727 thank you.I also told them I need to fly cut the pistons to work with the afr heads.or do you think I'm wrong? I really love the videos you share.
How in the world did that 331 make 448 with an xe274? Those heads must have been ported to perfection. You see I am trying to guesstimate my power. I am running a 331 with 9.6 cr and afr 185 heads with a performer rpm and comp 281hr cam with 1.7 ratio rockers. I figured it made 420 hp. So for my 388 build i bumped up my cam to an edelbrock 2281 ( 299 duration) in hopes of making 520 hp...your 408 stroker in the previous video only made 534 which made me think that no way my 388 would make 520, but maybe those afr 185 heads flow better than the trickflows on the 408.
that's why I test instead of estimate-I'm often wrong-the dyno never is.
*Great video!! What fuel are you using for these tests, specifically the last test?*
race on anything with boost
@@richardholdener1727 thanks!
Who did the work in the Victor e heads? What part number heads are they?
Total Engine Airflow ported them
QUESTION,FROM A OLD POST.HOW IS THE A/F RATIO TUNED DIFFERENT ON A N/A MOTOR WHEN USING E85 VERUS 91 0R 93 ARE THEY STILL ALL TUNED AROUND 12.9
yes
Thanks richard
What’s a good seat of heads to go with on a stock 302 with a 150 shot going with a e- cam
AFR, TFS
No intercooler on the Paxton efi combo ? How did you get away with that ?
WITH HIGH TEMPS AND RACE GAS
Should have tried a cleveland....just saying.
What is a good ratio for nitrous to na power. So 100hp nitrous jet for 250hp na for example.
50% power gain from nitrous works well (250 hp shot on a 500-hp na motor)
When you say HPPerformance are you talking about HPPerformance that was in NM?
yes from back in the day
@@richardholdener1727 They made some pretty good kits. I live here in NM. I bought one of their 03-04 twin kits on a forum a few years back and thought I got a good deal until it showed up. The guy shorted me the intercooler and some charge piping. I wish they were still in business. Unfortunately it's pretty hard to track down the pieces I need.
1.7 to 1.8 hp per cube n/a? that's asking a lot. i think 1.5 is very hard to achieve, or else my age is showing
We have to remember to subtract about 100-120 hp to equal wheel hp since these do not have accessories but still impressive
Did you say Ford probe pistons in the turbo 331 sbf???????
Probe (the piston company)
🤤👍
I just don't understand the purpose of running nitrous on the dyno
you should try it-its fun-plus its how builders tune their combos before running at the track
@@richardholdener1727 OK..... I get that part.
So can you confirm the myth that the LS was co-designed by a ford racer?
no idea on that-I do know it doesn't matter-every motor is good
@@richardholdener1727
I can't find the article. The website is down. I took a screenshot of it years ago but that's on an old phone. If I remember correctly it basically said the LS has many Ford attributes such as bore spacing, head bolt pattern, deep skirts, cross bolted mains, firing order, etc..... because it was designed by a Ford guy. I think it was Robert Yates that had a hand in the head design specifically.
Supposedly the LS head bolts onto a sbf but it needs some Frankenstein parts to make it jive.
block splitting is due to to much rpm
HP sells cars Torque wins races
Only in countries where a race lasts no more than a few seconds and people don't know how to drive a stick shift.
Not a big fan of Ford either... But at least your showing guys ford combos that a make big power without going LS all the time... Keep ford with Ford... Can't wait for that 455 Buick again🗣️🗣️🗣️
Lol, low compression? How bout 13:1 with twin precision turbos, 22psi boost, carburated running meth, around 1300hp to 1500hp. I dont get why guys still build engines that run below 9:1 compression ratio. If you have proper fuel available from the pump, or the car wont be used as a daily, give it compression. Id like to hear your opinion Richard.
Im thinking about playing with high compression and some boost, but will be on a 4 banger. Highest octane here in my country is 95 unleaded pump gas. We dont have many options when it comes to v8 engines. A run of the mill old school small block engine will cost you more than buying a 1uz and swopping it into the car, including everything you would need to get the auto tranny shifting and tuning. Hence every 2nd pickup here runs a toyota 1uz.
for a race motor with enough octane, more compression adds power-many of these were done 20 years ago
What did you use to tune these fuel injected 5.0L’s?
holley
Too much horsepower is just enough!
Personally I blame squirrels
Ahh there it is
@@xmo552 😎🐿🐿
Waaaayyyyyyy too much valvespring............ 250 seat 760 open dual spring would have worked to 8000+!
On the 427w
That's 427 needed different heads. Y'all threw up money on some garbage heads don't matter how much the flow bench test are. Afr 225 or some kasse p38, trick flow r or high port. If I did n new motor would be aluminum 363 dart block with some AFR 225 outlaws and 1 turbo for mild street motor of 800hp/torque or race gas for 1000hp.
you missed the point of the 700-hp combo video
@@richardholdener1727 nope. Crappy heads waste of time and money.
Rich, im beggin you, please find a different song!
Great vid otherwise!
Come Back To Chevy!!!!!!
I test everything
@@richardholdener1727 Well then.... how about an old 4.2 XK Jaguar twin cam hemi, with supercharger, turbo and on and on....... Would love to see one of these old motors but never will.
I can use a 10 test std panel 😂
