SCSTRANSPORT, I know what you mean about heater cores. I gave up on a '66 Ranchero precisely because of all the fuss with a heater core and of course I should have hung in there and got past it somehow. An even worse case was the replacement of a windshield on a MG midget which had bolts where I could only get two fingers and after about an hour on each side I was sure I had whittled away the rest of my fingers on the edge of the sheet metal, but I finally got the nuts started and a long-handle box wrench did the rest. Well have fun with your 390, it sure sounds like an impressive street machine. Just think if Ford would have kept the same bolt pattern on the bell housing and adapted the ARDUN heads with just adding two additional bearing webs in the block the way the Dodge Red Ram hemi did. Then the older engines could have bolted on the newer heads AND the new blocks would have been stronger. Hind sight is 20/20 but the crazy thing is that it could have been done! Give me a time machine and after I make a lot of money on past lotteries I will go back and fix this problem!
