Aluminum Head / Cam Recommendation needed for 1972 Blazer K5

[MARKDTN]

I'm going to go a different way and say go find a 96-99 Vortec 350 and buy an aluminum intake for it to fit a Q-jet. You get great heads, factory roller cam, 1-pc rear seal and other than center bolt valve covers you can't tell it from a '72 350 once you paint it orange.

All '72 accessories will bolt up. You just need to be sure that the distributor gear is compatible with a roller cam.

As far as A/C you probably just need a Sanden compressor and bracket kit and a hose kit to hook to original A/C stuff in dash and condenser.
