Tim, there is no frame in the garage, only a engine. This gentleman is wanting to know info on the engine and it also has my curosity. The crankcase vent turns toward the firewall and then down on a angle. That is just like the vent on the 52 coupe powerglide that I looked at. The motor mounts are on the side of the engine and not in front. So, I am sure it came from a car and I am pretty sure it is a 235 low preasure. If I get a chance I will try to get the other numbers to determine what year of car it came from.
