sprintfire pistons
I was wondering if anybody has tried using oversize spitfire, invader pistons in a sprintfire? I have a set and am getting my cylinders bored to try it. I'm not sure if the rings will stand up or not.

Re: sprintfire pistons
It will work but, the rings will wear out rather quickly. It's better to find NOS ones or good used ones. Wiseco used to make 340 pistons but, they stopped a number of years ago. I've got Wisecos in my Spitfire. They are single ring pistons. They're Wiseco# 2042s. They come with CDM rings which can run in Cast, Chrome or NiCaSil. If you can find a pair of those, that would be your best bet.

Re: sprintfire pistons
with the pistons being oversize, are the rings still designed for a chome bore? after boring the cyl. it would have to be replated. I was thinking that the rings would be designed for an iron bore, eliminating the need to replate.
