" From: "Jim Boone" fljab@xxxxxxxxxxx " " " " Take an already light '64-5 American, put a turbo'd aluminum six in " it, back it up with a Mustang V6 5 speed, put 3.31 or 3.54's out back. " That could be fun AND unique! You should be able to put ~10-12 psi " boost to it with no problems, maybe ~300 hp or so if set up right. one thing hits me - clutch size. you'd have a challenge getting 300hp through a 9 1/8" disk! and the 196 flywheel isn't drilled for anything bigger. it is the same size as the '64-'70 though, so if it's thick enough in the right places it could be drilled. they have the 10"/10.5" pattern. hmmm... maybe the flywheels are similar enough that an early 199/232 one would bolt on without much work... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
