Re: How do i convert to V8?
Look to see if the tranny/bellhousing is one unit. If not go to the bone yard and get a bellhousing from an '88 or newer full size with a V8. The Borg Warner T's will, not only bolt right up to that bellhousing but, handle an engine with up to 300ft/lbs of torque. I put a 283 into my '83 with the original 4 speed. I am going to upgrade to a 5 speed shortly. You will have to get a clutch kit for (I think it was) an Astro van. The splines were the same and the size of the friction disk was, very close to if not, the same. Advanced Adapters is very spendy. If you have the $$$ or do not have the resourses or the time go for it!
Good luck, let us know how it turns out
