Well I picked up my cam today. After spending some time at "The Speed Center" (our local hot rod shop) I settled on an EPR mc1713. The guy tells me this should make the truck sound real nice and getbup and scoot just fine. Well see. Anybody currently using that cam?
.050 duration
intake 223
Exhaust 223

VALVE LIFT
Intake 447
exhaust 447

Ill recap what I have for the motor now too.

Its a 79' 4 bolt main truck motor, with stock heads fresh valve job, hardened valve seats and new exhaust valves. Block is bored. 040 over. I have an edelbrock performer rpm aluminum intake and im planning to run an edelbrock 1406 carb. Flat top (eyebrowed?) Pistons. Also Have HEI and Im going to be doing an MSD 6A Box

Is there a way to calculate horsepower without using a dyno based on the specs I've given? Finally, now that I have a new cam should I change the springs? They're all very tight. Thanks in advance everyone!!
