355 Build

[srich1207]

hey guys I am needing some advice on what cam and what heads to put in my truck. I have a 72 C10 with a Turbo350 with 3.55 gears. this truck is my toy that I will drive maybe once during the week and sometimes on weekend. I won't be doing any towing, I am wanting a cam that produces good low to mid-range torque, this truck will rarely if ever see 5000 RPM's and this is what I am thinking about and yall tell me if I am on the right track.

355 Small Block
Stock Bottom End
Flat Top Pistons (with 4 Valve Reliefs)
Comp Cam HE268H
Advertised Duration: 468/468 @.050 218/218
Lift: 454/454
Edelbrock RPM Aluminum 2.02 64CC Heads
Edelbrock Performer EPS Intake
This was on the truck if I can use the RPM Air Gap and make more torque
let me know
Edelbrock 600 CFM Carberator

I am calculating that my compression should be somewhere around 9.3-1 I know there are more factors that go into figuring that than what I have but I think that will be pretty close. What I am after is a good sounding cam, but I still want to have good vacuum at idle so I can run power brakes, AC, Power steering, etc. And also does anyone have an idea of what kind of power HP/Torque this will produce and if it will have good vacuum.
