Thats a fact. but, if your going to kick it up a notch, (V8 or turbo 4), you might be interested in an 8.8 . besides, add up all the cost for parts and labor to convert that 8" to the 8.8 specs listed above. I am quite certain it will be quite expensive... much more than an 8.8 out of the wrecking yard. let me give you an example, I recently bought an 8" out of a 68 ford falcon. I think I paid $150.00 or $200.00 for it, sounded like a great deal. I was going to put it in the pinto. but first I wanted to rebuild it to 8.8 specs. a local shop wanted in excess of $500.00 to do the work, parts plus labor. when all was said and done I would have over $750.00 in a 8" and still not have the rear disc brakes, and are the grenadas 5 lug ? so the bottom line was, I could buy two 8.8's for what one 8" would cost.... no thanks, I'll go 8.8....
