MX6.0

Stock LS2 bottom end with stock unmilled LS3 heads, intake, injectors
EPS 222/230 .591/.608 114+4
25% underdrive pulley
spec super twin/AL flywheel+PP (36 lbs total)
No a/c, no p/s
GTO t56
3" AL driveshaft
3.23 getrag clutch diff (cts) / 24" tire
1.5" primary, 2.5" collector, Shorty headers -->2 cats, 2 resonators, muffler with 2 in's and 2 out's

I'll probably try to fab some 1.75" or 1.875 long tubes this winter and maybe have the heads milled a little. Should be worth some good HP gains.

Sure thing here it is. We lost tach signal for a second which is what peaked the torque, on the pass jsut before this one it made 454 tq. This pass looked to be even higher on tq, but the tach signal messed it up. but anyway here it is.

Love this thread...Im in search of a Lq9 or LS2/LS3..I've been searching for complete takeouts and they are somewhat reasonable on prices for the Lq4/LQ9..I can buy a set of L92 or 243 heads. All im wanting to do is put my 1987 caprice LS in the 11s and have it as a pro touring deal. With some of the threads on this forum I think I can get there.
