Check your fiberglass cowl firewall to motor clearance I think that’s the passenger motor mount bracket and your motor is to far back.
If it’s marked LT and the other is RT it’s a Classic Roadsters mistake they did a lot that way.
The rubber mounts are installed opposite of Ford use on purpose by CR also.
The big block frames have equal toe room on both sides of cowl about 12”.
I will double check on the brackets tho, mine are marked, but I remember I used the mount welded in the middle as drivers side.
For what that’s worth.
