The 'trick' to making any 4bbl work with an adapter(sq bore to spread bore)is:
a)most adapters require hand grinding to the front and sides of the areas closest to the primary bores,
b)hood clearance between the under side of the hood to the top of the air cleaner,
c)open center gaskets above and below the adapter,
d)lengthen the accelerator cable and re-adjusting the kick-down linkage if running an automatic trans.
It just is not that big a deal. And in many cases, it does help performance, David.
