Couple pictures that may help you decide. I just finished this 63 with a 454. I ran with 68-71 Chevy truck BB mounts. Although you can use what you have but it keeps the engine back far enough you will need to dimple the firewall. The mounts I used bring it forward enough to run taller valve covers. Everything clears well. I don't see any problems running the stock heater box.
