Vegeance Racing built 1999 427 C5 Corvette... Videos/Graphs/Pics inside This is a nice example of a VERY docile street engine that makes plenty of low end power/torque and drives EXTREMELY well. Our customer previously had a 404 LS2 stroker built by another shop and had nothing but issues with it. He decided to build a new engine instead of repairing his 404. The only thing used from his 404 build was his cylinder heads. We sent the LS3 cylinder heads to Total Engine Airflow to be CNC ported.

Why does it fall so hard after 6k? My turd is just a H/C/I LS2 Stock short block and it doesnt fall until 65ish... Heads? intake outflowing heads?
I always thought bigger cube motors reved much higher...

i don't know if there was mention of the cam specs during the video, but the cam selection would be a huge indicator of where the curve "stop". From the idle clip, although my speakers on my computer suck, it sounds extremely mild and definitely based more towards a daily driver, street racing kind of cam...Good work Vengeance, i'm sure that car is a blast to drive

How much would CNC ported LS7 heads/intake pick up with an LS7 specific cam on this setup?
I have stock LS3 heads/intake on my 12:1 compression 438ci setup and it made 528rwhp/516rwtq on a dyno that reads about 30rwhp higher than a Dynojet.
235/242 x115 cam but it has mid length headers on the combo.
