@@dondotterer24 thank you
Do you ever test with 93/ 94 Octane Fuel? How much of a Gain could be had from it?
In this case it would have made zero difference… with only 10:1 comp
Looks awesome! I'm currently doing the same thing to my E7s. I noticed you cut down the intake guides a bit?
What’s the best 358 sbc for circle track. Bore and stroke?
Bro this is some wild ass shit like you can really gap hellcats 😂 I had a 01 5 speed echo coupe 😈💯
@@Jdmstreetracer I went for a ride after the dyno lol 😂 that short wheelbase and with that power felt like a rocket 🚀 loll

I have been doing this since 1971 on dual planes..waste of time..the engine dyno shows this.All you have to do is add a small spacer and it accomplishes the same thing as is moves the carb away from the divider to help the cross flow.
@@johncunningham60 when you have no hood clearance is when the issue arrives for a spacer ..! Agree 👍 with you
Any hints on the camshaft specs? Awesome results for such a streetable camshaft.
That badass 10k rpm circle track 35k Chevy probably had many hours of laps. At some point someone may have retorqued the heads a smidge to much later in it's life causing the intake valve slap(and your opinion & description is also phenomenal) regarding the degreed improperly timing gear.
@@kryptoknight1667 I don’t think this engine ever spun to 10k … re-torquing or even higher trq spec will not make the quench tighter the issue was the camshaft was never degreed in from the guy that refreshed it previously and the camshaft was one tooth off so about 20* advanced there for the pistons where making love to the intake valves … thanks for watching ✌️
What size is the Engine?
@@hpjunkie69 4.075” bore stock stroke LS3

I heard a lifter,the ls curse. What lifters do you use?
@@davidreed6070 ls7 in this one
@@georges8secpony I have been using delphi in street engines, all fine so far.
@@davidreed6070 me too not one issue so far … for 8000rpm boosted applications I like the Johnson or caddy GM ones
Cathedral ports always made good power...us ford boys know very well...nice build
Great stuff! Do you guys build the engines and port heads as a service or is this more of a personal project? I have a racecar with a LS1 in it thats on its 5th year of use, checking my options for when it eventually goes (would rather rebuild than put another different engine on it, its using the stock GM ECU).
@@Vittinable thanks ., we been in high performance business for 15yrs as MGR performance … we build engines tune them go ra big with clients and we have a reg mechanics garage 3 lifts up front … so we are busy all yr around none stop
@@georges8secpony great, will give you guys a call when the time's right then!
Que tipo de gasolina
@@davidguillen5189 91 octane pump gas
Very impressive. Have you watched Eric Weingartner videos on the LS cam challenge?
Thanks ., no I have not watched … I have build and dyno tested 100s of this engines ., each one I build is specific to client needs so I pick or even spec my own camshafts …
@@georges8secpony You do a great job. Well thought out combination.
@@dondotterer24 thank you I try
YES SIR!!!!! AWESOME!!!!!
Sorry for the F bomb … I was excited
What about one cylinder have do v- groove ??
Healthy what's heads are on that thing?

Hey Stuart thanks for watching ! Trying to manage getting work out we are really busy and been around for my kids sports events… very little time left but I will try to post more often ! Thanks for your support
🔥beautiful 🔥👊🔥🔨🏍⚠️⚙️
Nice!!!!!
Awesome George. 👍 💯👍
Nice!!!!
Some machinest moved bbc heads .100 over, and.100 up on a restricted engine and gained 60 hp.
Hey George, what small-bore LS3 head do you recommend for 5.3/4.8 bores and for 5.7 bores?
Hey buddy for the money the Promaxx small bore is very good 👍
@@georges8secpony anything you don't like about it or did you already review them?
@@2drtahoefan1 like all Chinese casting you have to check valve job seal and deck straightness that goes for any new head actually
Good luck my friend... appreciate the content. Respectfully, Seth
@@sethhughes2163 thanks 🙏
Nice runs George.👍 The Mustang sounds great. Making big power.👍 Good to see you back on. Have a great day.
@@edsmachine93 thank you sir .! Sorry I haven’t been active here ., been trying to get my self in shape and i was in Greece for a month on vacation ., so once I was back I had to work double time loll … I’ll make a better effort to post more often .! Thank you for the support much appreciated
Great idea on the dimpling where the air gets sorted or shared. I have this same intake so ill be taking this for some gains, thanks for showing!
Thanks for watching!
How will that affect the head gasket on offset bored bowtie block?
Using 4.200 bore gaskets ., and yes that’s a bow tie
🧈
My man....nice work. Question for you if you don't mind. Why not a larger corner radius on the intake runner? I've never ported a Vic Jr so I'm not sure if that's physically possible.
@@arturozarate1752 they are pretty much this way from factory …
@@georges8secpony ah ok. I find very little airflow in small radius corners like that, and I have a client wanting to use a set 418w build. Thanks for the flow data. The AFR 205's of that era seem to be a close if not better head. I wonder what the side by side comparison would be. If you ever get the chance I'd like to see that.
@@georges8secpony really good data flowing the port all out. A lot of people don't understand the purpose of that. Where was the turbulence? High speeds over the short?
What's your prices on something like that
I only port manifolds and cylinder heads for engines I am building for clients ., unfortunately I don’t have the time it’s very time consuming … thanks for watching
Mopar guy here " Direct connection sold an X block in the 70's that was a 318 that you would bore to a 340 with plenty of room . 4 bolt main caps, extra webbing around the lifter bores High nickel content block 750 Hp Capacity 9000 rpm limit A true racing block for the enthusiast " Put a set of TA 340 heads on it with the offset roller rockers . Late 60's Dash 3 steel truck crank 340 TA rods , A Torker 340 intake , Holley 850 carb and the 528 Purple Shaft solid cam , sold by Chrysler Hooker Super comp headers . Had one in a 1970 Duster . Ran 11.7 all day with 4:30 gears for many years on 93 Pump gas ⛽ All off the shelf parts , No sectets needed , Hellcat performance at yesterdays prices 🥳
The pistons are too short and unstable. It makes for a short lived engine.
What carb are you using? And mods to it?
CSU … most of the time Kevin gets the super close
How’s oil pressure with new clearances and high spring ?
@@taptoretry7335 about the same as before …
Is there anyone around who knows what they are doing that will still port E7 heads?
Lost the part 2 😮 where is it?
You 💯 on the money as far as it was angle milled , here in Pennsylvania we race late model dirt track racing and thats one of my engine builder did cus i was on a budget, he milled my heads so it was the same as a set of 18° heads i used a Edelbrock 18° super victor intake and it made good HP
Those holes in the roof of the exhaust port......what are they from or for?
@@VGHCX egr
Sure would like to see one of the pistons out to see what they look like.. got to be short with that much off the deck and a 6”rod.👍🏻
OMG THAT THING IS FAST !!!
Will you disclose the ET ?
Sorry N/T car I cannot
🔥nice setup, she’s ripping🔥👊🔥⚠️🔨⚙️🏍
What do you set rod bearing clearances at ? On this motor ?
Man I’ve had nothing but bad luck with my current engine builder. What do you set your main and rod bearing clearance at for a 1500hp steel rod sbc ? Any help is great thank you .
Between .0025-.003 on both … again if all measures straight and round and you trq every main and rod with bearing in it and measure and measure every journal you will only then know what everything is … it takes me 10hrs of measuring and another 10hrs of assembly never mind machining etc ., this is an average build let’s say add jesel belt drive and shaft mount rockers etc there goes another day … most people don’t wanna accept that to properly build an engine it could take 3-4 days … most don’t wanna pay for quality because their next door neighbour can do it in a day …
@@georges8secpony okay I had mine setup at .0025 on 2 motors and it kept cooking the bearings. It seems to tight for 20w50 oil
@@taptoretry7335 détonation can wipe out bearings also …
@@georges8secponyno signs. For some reason oil pressure was really high 150psi. All showed heat besides one . Don’t think they were all checked
@@taptoretry7335 150psi oil pressure !? With .0025” clearances !? What engine is this and what oil pump your using
