since i'll probly be up around 150,000 miles when i do the swap, was figuring I would have to rebuild the tranny anyway...some HD parts in the tranny should hold it I think, but I know i'll be close to the limits on the tranny....hadn't thought about just swapping the intake, that's an idea....not sure if the original computer is in mine or not, so if I had to change it wouldn't be a huge loss... Thanks again guys, and sorry for being ignorant on the 70's engine, little bit before my time...
