I believe I read somewhere that a Mark IV crank can be used ib a Gen V block thru use of an adapter??? Is this true? If so, where/what is a source & part # of the adapter?????

Also, looking for a std bore Mark IV or Gen V engine (either-, crank used) or block , crank, pan, heads (if gen V) .

rear main seal
that's where the diff is.

Yes, I know the seal is much larger for ge blocks. But is there an adapter??????? Inquiring minds have to know!!

Seem to recal something like this in Mr. Moores book

i know theres one for small chevy,pretty sure there isnt for big chevy!

This setup is what I have. My engine builder ordered it when he assembled short block. It is 2 pieces of alum. that go where the rear main seal is. New block wants a 1 piece rear seal where crank is for 2 piece seal. Have had for 3 years now & no oil leak thru rear main seal. If you need I can call & see where he got it.

Chevy HiPo catalog has it.

Blown- Here is what I found out. Looking at picture it looks like the part # 8736

Part#8735 or 36 $87.95

I will try I see where mine was gotten from.

Perfect Turbojack!!! Exactly what I needed..... now to find a Gen V block, pan & rectangular port heads!! ?????? anybody???

If you do not have a block,then you want to find a gen 6 not a gen 5 block.
