350 LT1's in the 11's? I just got my car into the 11's recently. Best pass was an 11.72 at 114.44. My car has a BONE-STOCK shortblock with a cam/heads. I see TONS of 383 LT1's in the 11's but not many N/A 350's in there. I figure with a new tune I should see 11.5's easy. We just put a single plane intake on it with a custom elbow, and had NO TIME to tune. It didn't have the best throttle response and ran a little stumbly. It was acceptable, but just not crisp like it should have been.
Anyways, my question is this.....How fast has someone gotten a stock block 350 LT1 to go N/A?

I figured there were quite a few. I wish the top 50 lists were as complete as they are for the LSx cars though, I guess us LT1 guys don't take it as serious. 10.4 is hauling ***, I'd like to know the details of the setup. I have some weight reduction to do yet, but I'd have to hit a PERFECT day, with pristine weather, and the rest of the stuff I don't have yet (k-member, a-arms, manual rack) to see 10's. And by that I mean a 10.99, just squeaking in.

Daniel Stockheads are sitting on shelf right now. If i ever decide to get serious for the stockhead record I would go with weight reduction currently 3325 with me in it,Radials instead of Bias ply tires,more gear,and more converter. For now I have some lightly ported heads and i'm doing a lot of bracket racing not concerned about all out runs. Current setup running low 11.20's at 120 thru mufflers in bracket mode. Frank95z

Joelster how does the XFI cam perform for you. I ran the CC306 with around the same amount of mods as you with bigger heads. I only got a 12.1 out of that setup and was thinking of switching my cam to the XFI 468 but all I heard was bad things.

I really don't like it to be honest.Mine is about a year old and is ground on a 114. I guess the new ones are ground on a 113. I would bet that a slightly smaller cam on a 110 would pull just as hard up top.
