Can you help with engine build?

Ok so quick rundown, my daily driver is needing more work and done putting money in it. So it will be sold and all funds go into the truck and it will be my daily going forward.

It's a 1972 GMC C20 with the stock 350. It has HEI already installed.

The plan is strip engine down to bottom assembly. I have stock vortec heads that I am going to install. I am not changing springs or doing anything to them other than valve job and resurfacing them. I am doing this on a tight budget because I need the truck soon

For a cam I have a torquer cam specs are 278/288 204/214 @ .050 .423/.443 lift
Also use an edlebrock performer rpm vortec intake.


My big questions are this, opinions on the cam? Anything to consider or worry about with the stock vortec heads?

Also what has everyone used for a carb with this head swap? I can't use the stock divorced choke because the intake doesn't have the setup for it. Anybody convert a divorced choke Rochester to manual or electric choke?

Main goal is I need to do this right, but tight budget. Any help would be huge. Thanks
