To hit the 425-450 area with what you have I think it will take a hyd. cam with at least 240 at .050 to get the job done.Quote:

i want to use truck as one rank street truck that sits in garage most of the time. on saturday nite go out and beet up on ricers with my truck, also may go to 1/4 mile strip occasionaly. what about the combo i discribed? dont think i can go over 500 lift with the springs i have
Time for bigger springs.
If you have one of them around, let me know!!!!Quote:
