Quick truck, good luck on the 13's, I don't know though, my friends 3,300ish lb late LS1 camaro with the better intake manifold, headers and exhaust, ram air only runs a 13.0.
EDIT: Never mind I thought you said 13.0.......breaking into the 13's seems doable!
Thats what I thought, I was expecting MAYBE 290hp to the tires....
It is a Stock heads/cam LS1 from a 1998 corvette, If I remember right the cam is one of the smaller LS1 cams.....479/.467 lift if I remenber right.
The truck ran a 14.0 @ 94 mph before a few small changes, but at the time had 3.90 gears, stock 4l60e with a sloppy 2-3 shift, ported oem throttle body, headers, flowmaster muffler, and custon home made intake
Since that 14.0 pass I added a UD pulley(maybe 5 rwhp) LS6 intake manifold(maybe 8 rwhp) fixed the 2-3 shift by rebuilding the 4l60e with the high rpm pump spring kit. and the dyno tune of coarse(15hp) I would think It will hit 13.7 or so with the same conditions as the 14.0 run...Again on the 14.0 run I would feel the truck slow down/bind up on the 2-3 shift...now it is a nice quick kick into third with ZERO hesitation.
The 3.90 gears help my truck alot, I think the good combo of bolt-ons help this stock motor show its potential.
