i'm trying to finish the 2 to 4-bbl intake/carb (weiand 4-bbl/holley 650) swap this weekend on the 301. the "trial fit" looked good but now i'm seeing that the holes are a bit off. i know my grandpa had the engine rebuilt a number (15+) yrs ago, but the exacts on decking the heads and so forth are unknown. two machine shops have told me that there is no way to measure to know for sure how much to take off the intake to ensure an exact fit. they both said it was pretty much hit and miss. i cant hardly believe this. anyone have any experience with this before? thanks in advance. art
