The car was originally a small block car. So I am wondering, why he would have needed to do that to make it fit. Even now, with the "hammer adjustment" the distributor is super tight to the firewall. Does it sound like he used the wrong motor mount perches or could it be something else? Do BBC motor mounts move the motor forward compared to small block mounts?
Thanks,

I have a '69 Camaro with a 454 and the large HEI distributor and I did not have to dent in my firewall. I have about 3/8" of clearance between the firewall and distributor. I used NOS/original 69 Camaro BB Frame mounts(3980941 L, 3980942 R) and motor mounts(old # 3990918, new # 3962748). Your issue is definitely the motor/frame mounts. The NOS mounts also move the engine slightly(maybe 1/2") to the passenger side to provide more room for the exhaust header to steering box clearance.
