So I was lucky the other day and found a guy swapping a 350 in his 88 jeep and was getting rid of the 4.2. Picked up the crankshaft for cheap, but before I start sending it to the machine shop I just wanted to confirm it was the right one. I am tracking four counterweight but is there any casting numbers on it?
Also, is there anything else I would want to grab from him before he gets rid of the motor?

Re: Identifying 4.2 crankshaft
Seriously? You'll know when you see it and yes this is it. If you did a direct comparison against the stock 4.0L crank from any yard Cherokee you would immediately notice. It's that big of a deal. Only other thing to collect would be the original connecting rods(probably still mated to OE pistons) or get a new set for $$$.

Re: Identifying 4.2 crankshaft
Is the *3727 casting anywhere on the crank?

Check around the middle of the casting.

Re: Identifying 4.2 crankshaft
Well shit, it is a 5477 casting. Looks like the guy wasn't all the way honest on his motor. Can I still use this crank just have 10mm cut off the front?

Re: Identifying 4.2 crankshaft
I would use it anyway but I stick to v-belts(I don't recommend this for you). If you want serpentine that badly, figure out a way to fill the space between crank nose and balancer or grind the nose down to short spec.

Re: Identifying 4.2 crankshaft
Cut the snout off or just use a spacer, I cut the snout on my 12CW crank.

Russ has boxes of the spacers. Just snag one from him and carry on.

I'm sure you resolved this problem by now, but much easier than cutting the snout down. My spacer with the keyway cut in it makes it a quick fix.
