395 stroker small block chevy

This should be of interest to those on this thread: When the 408” FI engine now in my C4 corvette was on the dyno it was 600/615 HP @ 6.6/6.7 RPM.
TriY headers gave up a little on the top end but, really picked the torque up around 4K (thank you Calvin Elston). What was a pleasant surprise was
how accurate Engine Analyzer Pro and Dynomation simulation software was - they were within roughly one percent of each other on the HP and at what RPM but, a “little” high on the torque. Good data in good data out.
If you want to play with engines, these simulation softwares are dollars well spent.

What fuel are you using?
I would think also more duration with that compression.
I suspect a 1.7 rocker with that intake lobe to get 680" lift.
I think it would run pretty good for a dirt car especially out of the corners.

I run av100 ll gaz the cam has 645 in and 630 and on the card must use 1.6 ratio 298 309 240 252 at 50. 108 cl

What's the application? You might want to run a thicker head gasket. I don't know why you guys run that so tight, there's no advantage other than the small gain in compression, with the risk of the piston smashing the head.

Because he wants to shift at 6000 and will never see when things actually grow.......

That cam might make traction tough on dirt.

It is a circle track dirt application, it'l see plenty of heat. I still say there's no advantage to running it that tight unless it's to gain compression.

Dyno run result 641hp at 6800 and 541 ft torque not bad

[novafornow]

Was this with the small or the bigger cam?

[1127thunder]

Big cam

Curious, what they cost you, if he made a jig. I'd love to get a set of tri-y made for my c4. Got any photos, or other data of the build.

I think my street stock dirt will be fast with this crazy engines
