R16 Stroker Kit

[Brynt13]

This may be the wrong section so transfer it to the correct one if needed

I have a 68 SPL311 that I am doing a full restoration on and recently disassembled the motor to rebuild it. I'm wanting at little extra performance out of it and have read a couple of places that you can swap the U20 crank, rods, and pistons into the R16 block and build a "stroker" kit. Is this possible? If so what else will need to be changed? Obviously i'm thinking the cam, valves, and springs will need to be changed but is there anything else?

If you look in the Wiki, under engine swap and info, you'll find a good start. Also, search will reveal more stroker info than you could possibly use.
Good luck with your project.

Funny timing, I was going to put a stroker kit on ebay. Clearance ground H20 crank (guaranteed to fit if you block is in spec), bearings, reconditioned rods with ARP bolts, pistons, chain. PM and I'll figure out a price// jt

JT68: Are the roadster rods aluminum? Wondering from and interference standpoint.

Pistons are AL, rods are forged steel (original).

Anyone have any good sources for H20 crankshafts? I'm having a beast of a time hunting one down.

The whole stroker kit is 1250. Excellent turned crank .010. High quality Japanese pistons and rings, aligned-rebored-ready to use U20 rods, High quality main/rod bearings. Outright, no core charges! Jt
