389 Horsepower Possibilities
Hey guys, I was wondering what is the most realistic horsepower attainable with a carefully put together, nearly stock 389 using the factory exhaust and intake manifolds, a proper street/bracket camshaft still using the AFB.I imagine the AFB is the biggest impediment because of it's low CFM.
Is 400 horsepower realistic? Is 450 hp. possible with a good tripower set-up?
