Ok here's the deal my buddy just picked up a 99 z28 bone stock ls1intake to pan,it has a lid,headers full exhaust, stock converter and stock auto, 12 bolt rear w/ 3.70 gear. Went 12.1@116mph 1.7 60fts at the track on a drag radial. Does this sound right seems way fast to me. Car had a ms3 cam at one point and was pulled and the tune was left in the ecm would that have anything to do with it? I witnessed it and don't have the timeslip bc its not my car but I just don't understand how it went so fast.

a converter, slicks and 4xx gears MIGHT put him into the mid 12s.. unless your buddy was 100 miles below sea level 50deg outside and 0% humidity, I doubt his run was that good....just my .o2

Yea used to now has a stock. This I know for a fact. The ms3 went in his ls6 motor. I'm not trying to get in a debate I'm hoping I'm missing something bc it seems way to fast for bone stock, and I figure the tune still in th ecm would have hurt the power

It was like 55-60 deg out but I don't think we are that sea level. And dunno about the stall he said it was stock and since it don't flash, or have that quick rev like it should I believed him

Yea it must be stalled, and more then stock, you sure he aint lying about what it really has, his heads mighy even be ported and you wont be able to tell from just lifting the hood

Honestly the only reason I'm so concerned is bc I'm thinking of buying it from him. And just dunno if I should leave it or put a ms3 back in it. Orginally I had plans but it running that quick I'd hate to take it apart if it a stock freak

K like I said his a super close friend swears on his kids lives there's no spray drives this car car daily we only took it to the track bc his actual fast drag car is apart we were thinking 13s. There might be a stall idk but I can 100% guarantee no spray what so ever and the tune is from the ms3
