Breathing new life into the 318 in the Scamp!
United Engine says a perfect quench is .035". I'm going to try to get as close to that with my 383 as possible.....IF I ever build it. lol What I plan to do is zero deck the block (already done) and use the head gasket compressed thickness for the quench distance. Mine is going to be abour 10.4:1, but then again my cam is 270* @ .050.
