what else is needed for eleven second 340

intake= air gap
carb=750 holley
cam= 246@50 and 550 lift
3500+ stall
gear=4.30
tire 28"
1" HVH tappered spacer
msd mech advance dist
crane ignition
1.6 rocker
decent 1 5/8 header and open'em up
do a little port work and get the heads to flow at least 260ish at 600 lift. Use some good valve spring and run a carter mech fuel pump.

This should put you in the 11's pretty easy.
