1964 Impala Cam Select

[Grumpy]

a 64 impala. It has a 400 punched thirty over. 462 fuelie heads that give me 10.75.1 compression. With a 600 double pumperand EPS intake. This is a 4 speed with 336.1 diff.gears. Ok my initial question is how big a lift can i go with 1.5 rocker ratio? I want to burn some rubber. But it is for street. Power brakes too! Any suggestions? Thanks!

stock fuelie head valve spring clearance limits you to about .470 lift
, if the heads have o.e.m. valve springs they are easily 50 years old and probably need replacing,
in any case all clearances should be carefully checked.
