5.2 magnum vs 5.9 magnum right from the factory... same heads, intake, throttle body, exhaust manifolds, but the 5.2 actually had the "hotter" cam but the 5.9 still made about 15 more hp. I think you run a stroker now??? Why did you add more crank....????? :poke:
To manipulate my HP with less gearing and convertor for the few times I get the car out on the street, my track day's are long gone.
My old buddy traded his Chevy 383 for a 496 in his 70 Nova. lol
Him and I and a few other friends did the AHRA thing back in the day. It's been dead for awhile up here.
