SP XP Compatibility

[Oscar the Grouch]

Hi all,

I currently have a 1989 SP that burnt up a piston. Rather than ship my cylinders to SBT and risk my money on their "reputation" I have the chance to pick up a complete 1991 yellow XP engine with 150 psi in both cylinders for the same price.
My 4 questions are
-Can I swap my single carb manifold onto the XP block?
-The XP has a stick type cooling connection on the back while my SP has the oval type. Can I hook my cooling hoses up without issue?
-The XP has an extra ~1/4 inch barb coming off of the head while my SP does not. Can I route that out the same way my exhaust manifold water bleed tube is routed?
-Are the splines for the jet pump shaft the same?

Thanks!
Tyson

OR if you know of a good machine shop in the Madison, WI area to take my cylinders I'm all ears.

Here you go...
Differences between the 587 white motor and the yellow motor?

Sorry if I didn't clarify before.
Both engines are yellow. One SP(single carb oval cooling port no cooling barb on head) and the other is an XP (dual carb stick cooling port with coolant barb on head)
