327 build with mixed views on carburation
Built a mid 60's small journal 327. Engine specs are forged steel crank, around mains n studs, hydraulic roller with 1.6 rockers, 7372 magnum comp cams pushrods,dual stage springs from comp cams, a 495 cam, heads were punched to 2.02, intake is a 60's era streetmaster from eldelbrock. The question is carbs Cause I've got mixed emotions. Spec'd out anything over 700 cfm is basically pointless given how much the engine says it will use but I certainly don't want undercarburation either. A few options on the shelf are a first version edition throttle body Holley, the old ones with the user tuning adjustment on the brain. The throttle body is a 640. Second choice is a Holley double Pumper which is in the same range, or a vintage Carter afb which is also in the same range. Last choice is to go new and step up to a 750. I've messed around in the past swapping carbs on other motors I'd built but this one has a bit more time n money invested so I thought id see what another point of view may bring to the table as I'm always up for some new knowledge when it comes to motors. If I missed something lemme know its late but I've been thinking about that dang motor all day.
