: block swapping,crank sensors

12-30-06, 10:42 AM
I have a 98 sls with a y motor.One of the head bolt holes is damaged,I think beyond repair.Any rate I have a newer northstar 2000.or 2001 block.I want to swap the blocks,and transfer all internal parts,heads and so forth.The problem I am seeing is that the crank sensor holes are different. Does anybody know of a conversion kit,to be able to use the 98 sensors on the newer block.Otherwise,evrything looks the same to me.Also has anyone had to put a big sert into hole where the small sert didn't work?

There's no conversion, and there's no way to make it work.

You have to reuse your 98 block, or find another 93-99 block. Note that there are minor variations through the years, and the shortblocks will definately be different. If you just need the block though and can reuse your heads you'll be fine. I would seek out a 96-99 block to be 100% certain everything works.

:yeah: And I agree 96-99 is better. 93-95 Norsthstars might be iffy because of OBDI

I think Kevin (KHE) over at caddyinfo just Bigserted the block on a car he bought with bad head gaskets. The dealer who did the job prior to his purchase, did it wrong, which was the reason it was sold.
