If that's the case, you should probably knock out a freeze plug on both sides to do the drill bit test.

Okay,
After alot of questions he finally gave me a real answer. Here are the specs on the motor as he sent them to me.......

Ford 427 Medium Riser top oiler. Comes as a block, heads with rocker assemblies, crank, rods, pistons, cam, flywheel, water pump and oil pump. No other parts available. This engine has a 428 CJ crank and the block is .030 over. This makes 454 cubic inches and computer dyno was at 605hp. (trying to find the print out for the torque #s). The history of this engine is. It was originally built for 4x4 pull competitions. It was in a country modified whillys jeep. The engine came apart on a pull when the driveline broke and the whole thing was rebuilt with new parts. The block required number 2 to be sleeved and 6 had marks in the bottom that were determined to be acceptable. After the engine was rebuilt it began bending push rods. It turned out to be the increased cam lift. We went from a .640 lift to a .644 and that extra .004 at 7500 rpm was enough to kiss valves on pistons. I pulled it down to inspect for any damage to rotating assembly and found none. I decided not to continue pulling and the engine went under wraps. It has been there for 5 years now. I have moved it from my old shop to a storage unit and now it’s in my new shop. In the moving it acquired some surface rust. It is only surface rust and will cause no harm to the components. Below are the specs on the parts.

Block= 427 top oiler block # HP 31 \ C3AE \ 051-U bored .030 over

Heads= Medium Riser # C5AE-F

Crank= 428 CJ # 1U turned .010 rods and .010 mains

Rods= #C7AE

Pistons= Arias 13 to 1

Cam= Schneider solid lifter .644 lift 320 duration (no lifters included)

.... He was originally asking $2000 for it when I first contacted him but has since decided it is worth $2500 since he found the flywheel

Seems a little steep to me for a Top oiler that has been sleeved and may or may not have more damage. Pistons are usless to me also, so I believe my search will continue since I do not feel like paying to have it shipped all the way across the country only to find out it needs another sleeve or two.

I appreciate everyones help and input.
