what will it take to put a 235 with the 3 speed OD trans into my 52 3/4 ton currently sporting a 216 with a 4 speed that is essentially a 3 speed due to the granny 1st gear?

i am aware of the t-5 swap; however i found an engine with the trans locally for what i consider a good price. definitely competitive with the t-5 and less reengineering. if it's an easy swap i might do it.

thanks
