Engine swap

Asked by Oct 11, 2017 at 02:51 PM

Question type: Maintenance & Repair

Recently bought a 77 Grand Prix. I'm currently
working on trying to upgrade a few of the
components under the hood, and was wondering;
What size engines fit in this sucker?! Can't seem to
find any forums or websites to help. Would like a
427 big or something of that nature. Any help
would be greatly appreciated.
