400 BB
It has a nice rumpity rump idle to it so I'm sure it has a cam in it. I bought the car from a used car dealer. It was someone's toy at one time. Stripped out interior, stall convertor, full manual reverse valve body 727 with a 3.91 gear. May have been a Saturday night burnout at the local tastee freeze car. Not sure. I was going to replace head gaskets and valve seals like I do all of my used motors and run it as is. I have to many project cars and no time to work on them. Only reason I'm selling it.
