Jackson,

Where are you getting your measurement for the stock manifold? I measured mine at 3.125 x 4.25. The 2.69 for the front seems way too skinny.

:cheers:
Same method as edelbrock: straight edge across carb flange ... drop measure from straight edge to bottom of manifold flange that mates to block at cam. Maybe my manifold is different. My casting number on cast iron qjet manifold looks like 3973460 ... was on 71 L48 when acquired after many owners ... motor seemed close to original

jackson - do you use a drop base aircleaner with the Weiand?
No. My 71 has very low (base version for 71) hood & original 2-snorkel steel air cleaner w/ qjet & weiand 8004.
