Another Camshaft Question

I changed my car from power to manual brakes. You can hardly tell the difference in pedal feel.

You can still use the rockers just get a smaller cam. Mill the heads a little if you want some more compression.

Just the flow increase alone will make more power everywhere. Just don't over cam it. I just pulled an 8.5-1 440 with the Comp XE274 out of my Duster. Changed from stock 452 heads to cnc ported 440 source heads I had lying around and it was a night and day difference.
