I know that a number of people have done the V8 swap on the Astro, but I was wondering what engines other than the 5.7 fits the Astro? Is there any other engines that match up with the transmission? I would like to put a newer more powerful V6 in my Astro if there is one that is an easy swap. If not what would be your suggestions for a possible rebuild on the 4.3 to pull some more HP/torque from it while keeping it streetable?
