Trying to make sense of the casting numbers on the engine blocks
So I have a engine block with the casting number 53008405, and a date of 6/27/90 on the drivers side. On the passenger side there is a stamped date of 006MX27 which I believe translates to 6/27/1990. It has crankshaft with casting number of 3003453. It had a cylinder head with a casting number of 2686.
From what I know about 4.0's this block casting number should be wrong?? Isn't it as follows?
year casting#
1987-90 53005535
1991-95 53008405
1996-98 53020569

4.0 Engine date codes
The date code is on the passenger side of the engine, on the block, just forward and up from the distributor on a machined flat surface.
The digits of the code identify:
1st Digit-The year (8 = 1998).
2nd & 3rd Digits-The month (01 - 12).
4th & 5th Digits-The engine type/fuel system/compression ratio (MX = A 4.0 Liter (242 CID) 8.7:1 compression ratio engine with a multi-point fuel injection system).
6th & 7th Digits-The day of engine build (01 - 31).
1. FOR EXAMPLE: Code * 801MX12 * identifies a 4.0 Liter (242 CID) engine with a multi-point fuel injection system, 8.7:1 compression ratio and built on January 12, 1998.

Dave, I've done a few HO into Renix swaps and every HO block was still drilled and tapped for the knock sensor. That's not a good reference.

Could I be safe to assume the crankshaft in the 93 work in the 90 block since they are both #3003453 cranks?
Does Chrysler always break the rules on casting numbers???

I built one engine using parts from 3 different engines, HO and Renix. Go for it.

Sounds great, but which main bearings do I use?
SEALED POWER Part # 7211M because it came out of a 93 block....or
SEALED POWER Part # 4289M because its going in a 90 block?
Just took the crank to get it machined, so I need to order my bearings.
