ive heard theres some adapter plates for these but i cant find them ANYWHERE does anyone know where id go to get one i need to adapt a small block chevy motor to a 78 ford 4v4 (400ford motor) transmission

There was a place called Transdapt years ago, they mostly had stuff for older conversions. Also look in the JC Whitney catalog, they have a lot of odd stuff like that.

ive tried to find a transdept one but theres all for like 30's - 40's style trannys ill try jc whitney didnt even think to try them thx for the help!
