Quote: I agree that while quench may be helpful, I just can't see how going UP in compression to get quench would work out for me. IF I were somehow able to maintain the same CR while improving quench, I could see that maybe being effective.
(1) I think the scr is too high & the gas (91) too poor to avoid pinging even with good .040" quench. (2) unfortunately that would take a piston change. Decades ago HotRod magazine did a build on a 454 chebby iirc work truck & they vastly increased the mileage & the tradeoff was it lost some power either low or midrange I dont remember & not sure if there was a pinging issue but I think the CR was too high also. I'd call a cam company & ask if that is feasible. It'd be 10 minmutes well spent. Unless they can grind a special cam I think it's gonna take lowering the scr with thicker gaskets & I'm sure a regular cam ain't going to fix this either
