Default 1970 350 vs 454

I am attempting to put a 454 engine in my 1970 vette that originally had a 350 engine. Is the firewall different in the cars that had a 454 vs the vettes that had the 350 engine.

thanks, Tony G

The firewall just seems to be about 3 inches forward due to the size of that BBC!
