My combo will include GM847, Ported heads, 4l80e (3800-4200 stall) and dana 60 3.73 gears

Anybody with an auto and the GM847 cam where do u guys launch at and get the best results.

i will be running MT ET streets on my stock 17" Zr1s. I know i will have to learn the launch for my specific settup. Just wondering where u guys are getting your best results.

u can also include 60 foots and ETs.

thanks alot

i believe the LE3 cams a lot like the 847, and lloyd recommends a 3600 stall for the LE3 cam.

 

The stall that i have just happens to be the one that came with the tranny. So i dont plan on buying another.....thanks for the input

anybody else??

 

id say launching at 3800 would be fine, but im no expert either. I would just mess around with what u can launch it at, and see what works best
