400 low buck dont give a

my build is similar, but different

KB240 pistons .030 over
block zero decked
performer rpm heads. milled slightly. 10.5:1 comp ratio
msd 8386 dizzy (has ign box built in, no external box or ballast resistor)
msd blaster 2 coil
performer rpm intake
holley 750 carb

i spent more... way more. but you could get closer to me by either swapping to KB pistons or by milling the head/block a bit to get your compression up (i wouldnt go over 9:1 with stock heads)
