I guess I'm a dumbass too for having spent my money on a N/A LSX454. Shoulda spent the money on a 346 with 400 shot and got the same results
Of course it's nice to have over 600 RWHP available everytime I stab the pedal....

sweet numbers, i may run that same top end if i can't find some ETP's i'm satisfied with
what valves (size and material) and springs were used in those heads? what did the DCR end up being? do you guys port LS7 intakes?

I think it is cool as hell. Not to mention, he could still spray the motor right? I mean, it isn't a nitrous motor per se, but It should be able to take a pretty decent shot? I would think it would handle 200-300 shot of N2O?
I would think that gets into the same catagory as they FI guys, while avoiding a lot of the difficulties. Again, not for everybody but then again thats why we modify the cars. If everyone did the same thing, it would be boring.

???
also, how close does the wrist pin come to the bottom of the bore? i know you can go 4.250" bore/4.5" stroke (so they say)...but the 4.100" stroke 4.200" bore combo you use seems to be pushing it, isn't it? i'm just curious. would this motor be safe on a 150-200 shot of N20? if not, what if it had Callies Compstar components in the bottom end?
i'm just curious
