M88 vs S38

[Dan101smith]

Can someone confirm for me whether the S38B35 is physically longer to cater for the dual-row chain, or would an S38B35 cam carrier bolt up to an M88/3 block and head?

Hi Dan
They are different by about 6mm. The difference is in the head, cam box, valve cover and timing chain chest. I had one of each at the same time and measured them both. You can see the difference if you look at a picture of the valve cover and compare the front section where the oil filler cap is located on an S38, it can't fit there on an M88. If you need a new cam box it might be cheaper/easier to pick up all the S38 parts and sell your head.
Cheers
Dave

Thanks dave, so the M88 block would mate up to the S38 head and cam carrier as long as the S38 timing chain cover is used?

I believe this is correct Dan. Has anyone on here done this?
Here is a thread that looks to be the vice versa set up.
