Quench?

I certainly understand your fears! You have to have the best rods. In my 331" SBC in my S/G Vette, I ran that squeeze using Manley Pro Pistons that we custom domed (looked like melted sherbet) with gas ports, .043 moly rings .100 down from the deck. I used Childs and Albert aluminum rods and just loved them. This was an engine used to seeing in excess of 10,000 rpm leaving the line and on the 5-speed shifts. We checked the stuff every two weeks. Even after 50 runs that clearance did not tighten! I used to check it by "laying on hands" on each end of the heads at start-up because if any thing was wrong, you could feel it. I saw Jenkins do the same thing! The engine also used studs everywhere and dead soft solid copper head gaskets to handle the 14-to-1 compression. That engine had the first sheet metal intake on it that I totally made for myself. That little engine powered the Vette to 9.40s at 146 mph. It was bad to the bone. It was on the cover of the June, '82 issue of Popular Hotrodding and featured full color on the centerspread.
