Sorry I did not look to see that there was 2 pages of post before I posted the above reply. I do have the perch you need and if you leave the bell housing cross member as is your drive shaft will work and you will use the rear set of holes for the motor mount perches. With a small block V8 your distributor will be close to the fire wall and fan will be a little far from the radiator. With that said I drove my 66 daily for 3 years with a 327 setting in the 6 cylinder position and even with an HEI Distributor and a clutch fan with no spacer the distributor cleared the firewall and I didn't have any problems with the engine overheating.
