I have a 70 model that still has the orig. block & head, running strong. I am about to add a new intake & a holley 390CFM Carb. Also going to do Headers & new exhaust at the same time. Any input from someone in the know would be appreciated, I'm not that much of a mechanic, but dive into everything headfirst. I have also yanked all of the smog & AC stuff, any issues concerning that? Thanks.
