I have had a ton of them.
- Original pistons are marked "SUPER" and are basically a CJ part, but generally hammered away due to detonation. You'll see a bunch of vertical wear grooves on the ring lands, especially the piston top around the edges.
- Rods are 390 rods, nothing special
- Crank is a good CJ crank, BUT, most of them run a multigroove pulley off the front and over time shake themselves at 2500 rpm and then have cracks at the 1/5 journal.
- Block is usually a CI/CX, but sometimes can be a C (very rarely) or no mark and usually have cracks on #2 and #4 mains at the main cap threads. Ironically, they can live a long life that way, but usually you have to tighten up the main cap registers and run a long stud for more thread engagement. Cap walk causes it, same reason as the cracked cranks.
- Not uncommon to be frozen and a broken valley casting, CI/CX a good casting after that but often a lot of core shift, so before you bore, sonic map the block
- I forget the head casting, but no good for anything
- Cam is a baby, I think like 250's adv, HFT, but I am not sure, but it's made for continuous low rpm duty.
- Memory says 205 HP or something like that, but I do not remember where I even got that number.
The mag is your friend, mag the block and crank. Pressure test the block, save the rods for a stock FE, toss the heads, toss the pistons.
In the end I like to find them, used to pick them up all over Nebraska, now guys tend to think they are CJs. However, I have never been amazed at the treasure I have found

...they are usually old spent workhorses usually and you pick through to find the good parts
