Took the offending motor apart. Bottom half of the rod was shattered. The remaining part of the rod was wedged between the crank and the bottom of the cylinder bore. The block is pretty dinged up at the cylinder. Piston will turn in the bore but not move up & down in the bore.

Theories

The piston rings froze, the rod shattered, BAM thru the block
The rod shattered, parts were wedged, BAM thru the block

Can I get a short block kit?

Does the cam look ok ?

If so it looks like you're in for about $300 worth of bits. (not bad if you say it quickly ... that would get you what for an F200 ? a crank ?)

Don't forget to get the end play shim kit. I guesstimated mine at about 0.020" ... hasn't blown up yet !

The rod bolts are still screwed into little hunks of alum. that used to be the bottom half of the rod

Have not seen the cam, or the top side of the cylinder yet

Fastermotors.com offers short blocks, kits or assembled

Going to call Terry I

The only way to bust a rod with intact rod bolts is to have something at one end of the rod keep going (The piston coming down under full force in this case) while the other end is stopped (the chain jammed inbetween the clutch and the block freezing the crank). So I definitely chalk this up to an external cause rather than any weakness in the design or the parts themselves.

Talked to Terry Ives. He goes with the rod freezing up on the crank theory. He was just thinking of making up a motor out of spare parts so I get to be the guinea pig.

He said he probably was not going to make it this weekend so he offered his motor. Cool!

Now the question is do I use his or Brads motor ?

Although I can see the attraction of Terry's Frankenmotor with a six-pack and turbo. ;D Just let me know...tomorrow is already Thursday.
