440 from an rv?

The tranny is going to have a shorter tailshaft and cable operated trans brake...you will probably want to source a different tranny....thus the kickdown linkage will be trash too....the RV's also ran some of their accessories different....specially the A/C...the good thing that if it the original 71 motor it will have a forged crank and heavy duty six pack rods....I am running a 73 RV block...I reused the crank and connecting rods.
