My rebuilt 440 has a custom crower cam with Johnson lifters and 440 source heads.Going hydraulic roller I needed to replace the springs that came with the heads.My machinist does not use comp except for there roller rockets.My motor has less than 200 miles on it.I am still breaking in the rebuilt rearend so I have not hammered it yet.The machinist has over 40 years of building street and race motors.Are you running power brakes.Having good vacuum for my brakes was a big issue for me.

I do not have power power brakes.  I have disc brakes, but not power, so vacuum shouldn't be as big of a concern.  How long did you have to wait for the Crower cam and what sort of specs if you don't mind sharing?

The cam was about a 2 month wait.Intake duration 270 with 511 Lift.Exhaust is 277 with 532 Lift.
