Finally broke down and bought a new HP document scanner to replace the one that died. So, for your viewing pleasure, a comparision of dyno results for the LS7 vs a couple 350 ci LT5s. Interesting...
First the base C6 Z06 w/ LS7:
From a couple years ago, I found this in the archives - Don's car (mods unknown) and Dominic's having the top end ported and ??? (he'll have to say what else). (He has a dyno sheet showing close to 400 RWHP after his last tune before he decided to widen the track by trying to push the guard rails out a little wider with his car

(I recon when he gets it running again with the S-II cams and now fully ported, another FBI tire-smoker will be terrorizing the blacktops 'round here!)
And, (as promised) this is my 350 LT5, fully (FBI) ported and tuned. What interesting machines these LT5s are!
I couldn't find any dyno sheets for some 415s, or 427 or 441 LT5s. But, if someone has one/some, and can post them for comparison, that would be cool!
