ok guys looking for some help here from some of engine gurus on this site. im kind of new to the turbo buick stuff although not new to engine building ive built quite a few engines in my career mostly chevy small and big block stuff and some ls stuff. I haven't gotten a chance fo flow a set of stock cylinder heads yet,but im assuming that they are like any other engine out there where the exhaust side needs help evacuating the combustion chamber. usually any time I build an non na engine I will run the exhaust side with a bit more duration to help evacuate the charge since the problem is not getting the air fuel in its getting it out. so to my question,why are the cams everyone is making for these cars all single pattern cams, ive even seen some patterns with more duration on intake side, scratching my head on this one. any way just wondering if someone could shed some light on this subject for me please,maybe its just because I haven't had a chance to flow heads yet and exhaust flows like gangbusters.
