C'mon. 430 torque @ 3100 RPM? No way. Not possible. Even the new truck LS 5.3 is 100 lb-ft less than that. Sorry, better check the dyno calibration as it is very optimistic.
It helps that it has been bored and stroked and displaces 383 cubic inches ;) Lots of 383's with aftermarket stuff do much better than that, but this was constrained by using the stock block, heads, intake and exhaust.
Compression ratio 9.5, designed for what passes for Premium gas here in Cali. Pistons are Speed Pro. Roller tipped stamped steel rockers and retrofit hydraulic roller lifters. Cam is a mild one, 218 intake and 224 exhaust at .050 lift. Intake manifold is stock casting # 3844459.

@dcairns61 That changes the whole picture! I stand corrected.
Engine sounded really good I might add.

Lots of people are tweaking small blocks to the 400 HP range without much more than Carb, Intake and Cam mods.
I guess the number of things you can do to a small block is virtually unlimited.
There is so much performance related stuff on the market that only the size of your wallet limits what can be done.

Stock Heads? are you using the stock steel crank? These are pretty mean numbers for a 327 not bad at all.

Nice engine. I had a few 327's. I've blown up all of them. I have 327 damage reports posted on my channel from the last 327 that blew up!

That's very cool. Can you tell me what you've done to the engine? What pistons, cam,intake manifold are you running? What CR does it have?
