Thanks guys I finally figured it out with your help.
This picture was when I first bought it about 95. It had a 460 in it and I pulled that one after the oil pump gave out. I put the 460 out of my dad's 75 Mercury in it had it bored .010 over, ported the heads, rv cam, dual exhaust with flowmasters. It needs an intake and headers now and a ton of body work but I am about to get a new shop so I can pull it off the frame and do it right.
Welcome to the site. That's a sweet supercab. Good luck and have fun on the resto. It's cool that you can do the body work yourself. I have a buddy who is giving me a pretty good deal on mine, but I would like to someday get another more budget friendly project and tackle everything myself.
