What would these cams do?
Looking at these two cams.
It will be for a 400 pontiac with edelbrock heads, rpm intake, headers, 9.5:1 cmp. Street car, weekend cruizer. 5 speed. A bit of a lope or rough idle would be fine, don't want it to sound wimpy!
Cam 1
Basically, RA IV cam
Lobe sep. 113 duration 304/316
Duration @ .050" 231/240 lift .470/.470
Cam 2
lobe 110 duration 302/302
@.050 242/242 lift .507/.507
Both are hyd. flat tappet.

cam 2 will sound better with the tighter lobe sep and be more perf with the higher lift.cam 1 will sound ok with the duration but the wide centerline will cause it sound weaker.

Thats what I was thinking. Do you think there would be much difference in terms of performance?
