I am looking for some ideas or help if anyone has put a small block chevy into a 67 mustang. I'm not trying to stir the pot. I like how the mustang looks but I perfer the small block chevy engine. Any help would be great. And I know and I've heard it before keep a ford in a ford. Well I know of chevys with ford motors in them. I'm not looking for vaule of the car but personal enjoyment. But this is my first mustang and made sure it wasn't a rare mustang. Its a coupe or a notch back. And had a 289 2 barrell. It was a C engine code. But had a pink 302 with a C4 trans in it when I got it. The car needs total restoration. But before I start replacing the floor pans I wanted to see if I needed to anything to the floor pan or firewall for space.
