My skin in the game is I own a aluminum 225, have a full length header still, have stainless 1.7/1.44 valves, have an aluminum 1 brl, 2 brl, 350 holley, 500 eddy, have ported about 5 or 6 slant heads, flow tested said heads and drove daily a built up 225 in a dart for almost 7 yrs. It was bullet proof, because it never went over 5500 rpm and I cross drilled the crank for full time oiling. It was stock and polished when I built it...looked the same 5 yrs later when I checked the rod bearings during an oil pan gasket change...leaked from the wind age tray I fabd myself at 18 yrs old.
Thanks again.
