HI Guys,
I have a '67 Chevelle project going on and I'm currently working on the firewall.. (body's off)
My question is this:
the small block is a 383 with a pro billet distributor.... will this clear the firewall? or do I need to work on it and make room before I set the body on?

thanks for your time!!

If you run a pro billet with an external coil, it will not be any bigger than the original distributor. If you are thinking of a coil in the cap, I am not sure.
