I agree with the bump steer problem now that I look at it closer. It occurred to me last night looking at this project that an easier way might be this:
We have access to a '65 GMC rear end,and I have a Saginaw 4 speed out of a 64 or so Impala. If we use these components and build a fresh driveline,there's really no reason we couldn't mount the engine/transmission about 8 inches forward of where the face of the transmission would normally be. The engine is easily that much shorter than the six is,and that would also enable us to set the motor a couple of inches higher in the frame,all of which will also get us more clearancefor steering,valve covers and distributor. I think this might also make a stock Saginaw shifter a possibility.
As for the exhaust,the owner's thinking he'll build a set of fenderwell headers,that will tuck in close enough to the frame and floor to leave plenty of tire clearance,and heavily insulate the floor for the heat.
We decided hanging pedals from a later(L. 60's/E. 70's) truck will give us the most benefit and options for brakes and clutch.
Now that the engine's hanging about where we plan to mount it,things are looking much better than when we started this project.
One more question-does anyone know if an adapter is available to replace the oil filter stand on a Pontiac with a remote filter? I know there's one that attaches in place of the filter,but I'll want to replace the part the filter screws onto. It's mounted to the block with 3 bolts.
And don't worry-we're gettong lotsa pics. I'll try to keep notes on what we do and what works/doesn't work to make this thing fly. Thanks to all who are offering their info,suggestions,and interest.
