I have fallen in love with '48 Ford Pickups, so that will be the car I am using it for, and the transmission, I would like to be a 700R4. Gear ratio is undecided, I can't decide how bad of gas mileage I want yet... I am thinking somewhere in the mid 3.'s, but definitely not 4:10's. The stang in the sig is my pop's, he started using this site as a restoration reference and now I am using it since we have finished. By they way, I don't know how to put a picture of it under my name, or in my sig, or in a post at all for that matter.*Any help would be appreciated* I am not sure exactly what the engine was, and I have no idea what it came out of. It was given to me, and the guy who gave it to me didn't know either. I looked up the numbers and they say it is a 1969 Pontiac 307. I don't know if the numbers would read as a Chevy or not, if it were. Well, theres the info, hope it gives you a little more to go off of.
