Nice build though. I'm sure that thing is ridiculously fast...

Yeah I've been reminded that I could have built a really nice 20B with what I've spent on these 2 engines. The LSx engines are the same as any other performance engine and when they break, they break bad.

Thanks! I haven't dyno'd it with the stroked LS3 but I'd guess its in the 450s. Its dead even with my friend's boosted C5 Z06 that makes 703 at the wheels. I've pulled a lot of timing because of the comp ratio to be safe. It'll get turned back up on the dyno. I'm hoping for 500 on race gas with the shitty headers I've got.

That's why I love tuned cars. Straight line, his $90,000 Z06 is comparable to the $20,000 (or whatever) build and it's not like Z06s are even that nice inside. Turns, I'll take a Miata any day. 3200lbs vs. 2500lbs...
