listen to dragula

he knows his shit

and just like he said most people run smaller combustion chambers now so they dont have to run domes..nascar engines run flat tops and are in the 12.1 range depending on the cc of the head and other things..my sb2 nascar heads i got right now for sale are a 36cc and the sb2.2 run around a 48cc range..a stock 350 engine is either 76cc or 64cc depending on the heads
