This is with mild headwork and a 270AHR then some bolt ons. Still has the stock intake manifold/internals/stock tune. My guess with tuning he could throw down another 7-10hp.
As for mine with better heads, same cam, edelbrock intake, and tuning. Probably put down 300-310rwhp. But thats just guess's
