Boom, this too is my next goal either in my nova or another gm muscle car. I reread this article all the time. Im guessing 25k gets you started! Lol. Supporting mods alone are gunna add up quickly
I ditched the 427 and am now building a 402 with a CCW ulta billet, and custom pistons.
Comp trunions suck and will wear and send metal through the motor. Get CHE bronze bushing replacements instead.
Gunna need more injector , at least holley 160s.
Who spec'ed the cam? Doesn't seem like your typical big boost cam.
