I think you should rebuild your cylinder head (w/hard valve seats),give it a set of rings and bearings and drill the front main cap as mentioned before. While it's apart do the full pressure oil machining. I agree with Belair about moly rings-they take a while to seat and if there's any taper to the cylinders it makes the sealing iffy;besides,you can put 100,000 miles on a set of cast rings without a problem if you keep up on your maintenance. Moly rings may last longer,but I don't think they're worth the extra hassles to make 'em seat well. And be sure to shop around for prices for your engine parts-there can be a HUGE difference in price of each part from one dealer to another.
If you go for a bellybutton motor,don't forget the 700R4,9 inch rear end,Mustang II rack-n-pinion,billet steering column,power windows,power steering,power windows,power disc brakes,A/C,big stereo with bigger amps and biggest speakers,etc.,etc. Just kiddin'. Don't think I'm opinionated or nuthin'...
Do whats right for YOU.Thats what it's all about.
Speed
