bellhousing swap

The first thing I would try is the 10 in scallopped clutch from Brewers Performance. Call them they have what you want. I swapped a 340 clutch, bellhousing and all into a 64 Barracuda years ago, to run a big block 10.95 scalloped clutch behind my 273. I did not have to beat on the car with a hammer. Brewers Performance has this system down pat also, if you want to go this way.
