Will those GMC 270 and 302 torque monsters bolt to a Chevy Trans? Do they need an adapter? If so, where can they be obtained? Anyone have experience with these great ole' engines? Comments on them are welcomed. Particularly curious about the 302 which were used in a 6X6, school buses and other trucks. They have heavy castings like the ole' International inlines of BD 240/265 fame. :confused: H.
