pretty quick...What's done to it? Was that on stock cam as well?

MrDestinE

oh no.... Here is a quote from the engine builder:
"It's basiclly a 0.020" over 5.7 with a 6.1 crank thats offset ground to give a 3.795 stroke. I set it up with a 268 cam, Our big chamber 6.1 heads and CP pistons yeilding a 10.8 CR, I ported the intake and slightly ported the throttle body. Other than that it's pretty much a stock 5.7"
That is a comp cams HR268....

He needs to set up a track intake and get some torque tubes. Hmm and get that tranny in there lol.

He's still having trouble hooking up, with a 1.7-1.8 60', once he can get those in the the 1.6's he should be knocking on 11's.
