Is your motor revving freely or does it seem to be revving slower than before?...maybe your rockers are too tight...if you think you have a vacuum leak..get yourself a smoke tester and find the leak.....Weren't you the one that was arguing with another guy because he said he beat an Ls1 and you said it was impossible...maybe impossible because your car isnt running right...

 

Uh, oh! A jokester here. Yeah I remember that guy. He had a completely stock LT1 and said he beat an LS1 and I called BS! My car has always ran fine until now. I have beat plenty of LS1 cars with just my bolt ons. This guy didnt even have those.

 

. "He had a completely stock LT1 and said he beat an LS1 and I called BS! "

I think you should re-read that argument...his car is far from stock...im not gonna argue about what you thought you read..

 

I guess you are far from stock to? Some peoples ideas of stock and not stock are way different. Some think because you have a 5'' tach. and a flowmaster muffler you are no longer stock. LOL

I dont remember the full story, but from what I remember I didnt think it was possible unless the LS1 guy couldnt drive or he had a lemon.

Anyways, thanks for not ruining my post!
