Why is it so hard to get good advice !!???

Use a long duration cam. such as a oval track cam. Worked for me with 10.5 - 1. 302- 465

Not long ago there was someone on this site selling 499 oval track cam kits for $90. I bought two just for this reason. Also disconect your vacuum advance and go with 15-35 mechanical advance. weld inner part of slots to 3/8 and take out the large spring.

This works good for the street but you will still need race fuel if you load the motor with sticky tires on a launch. Wheel spin doesn't hurt a motor.
