I'm playing around with the idea of a cam swap in my Challenger, nothing big just hoping to optimize what I have..

The Car...
!970 Challenger R/T Vert.. Heavy probably 3700lbs
3.23 gear which is staying, this is a highway cruiser not a hotrod
727 with stock convertor currently it with flash 2200ish
Stock exhaust manifolds to tips
Stock A/C, going to change to a Sanden compressor

The Engine...
Original 383 with 75K miles since O/H
.030 O/S KB 162 pistons .018 in the hole 5cc valve trough
with the current 906 heads C/R is around 8.2-1
But I'm changing to a set of 915 heads which have been cut .030 which reduced chamber volume to 76cc
New C/R should be 9.7
Current cam is the OE Resto cam
Intake is a Performer RPM & Carb is a Holley 4776 600cfm D/P
I've jetted it down four sizes & opened the PVCR's

I know the official stance is a heavy car with tall gears should have a vacuum secondary carb but it runs well & I accept the fuel mileage.....

So lets hear your thoughts...

I would not go over a 270h comp cam ,keep the the c/l @ 105,108 install at @ 102
Watch your push rod lenghts as they can be to short for a hyd situation?
Not much diff in your assumed comp pick up.
a little short on carb JMO
