NEVER use credit cards!
for my 66 tempest, 400 pistons are down 32 thous. will this affect me much? only going with a ra III or so cam, maybe a used 230/238 at 050 on 108 ls. not sure of the overlap. but with a lousey quench, 9:1 c.r. not very rad cam, would it really hurt if i didnt zero deck my block. zero decking would mean i would have to toss my heads (75cc)
