Yep! That's a little too steep for me also... If he really wants to sell those, he'd lower the price way down to 500.00 for the set... Even that is too expensive....
No wonder you rarely see a 2-bbl intake manifold out and about... I remember seeing one years ago in a Chevelle wagon being towed away to the scrap yard....
Some cast iron big block intake manifolds came with the Holley bolt pattern.... There was also a 2-bbl manifold in '69... Some 396 Chevelle/Malibu wagons had those....
