hi i own a 84 p-type supra and was wondering if the engine and tranny from the sc400 would fit

Hi dizzie!

All I can say is that you can ask automotive technician in your nearest place to check it personally. You can assure that you will not waste time, money and effort. Autopartswarehouse.com (http://autopartswarehouse-1.blogspot.com) has some information about car repairs. It’s good to read.
