Does anybody know just how much the LPG pistons add? I have a 292 with 3 Webber sidedraft carburetors, mildly ported head and bigger valves. Will the 9.0 pistons be worth the extra expense or is it just a talking point? The engine is a street engine going in a 1932 Chev. pickup weighing about 2460 lbs. Just looking for a good reliable engine with some horsepower for fun.
