Hi.
What engine is this? It's not a standard EVO. Looks like S&S but I don't see S&S logo on heads. Is there any way to find this engine displacement?

Welcome to the forums from Ontario, Canada, any serial numbers you can post.

It has 31/2 inch bore cylinders. It might have stroker flywheels, you never know.

Ultima . . . maybe?

I've got a brand new set of S&S heads and they DON"T have the S&S logo like I see everywhere else. As stated above start with the serial number on the case.

Found the serial number under the cover plate. Looks like it's a standard evo. Also found this on heads - HD 86(or 98) which probably means that heads are also standard

I think you have aftermarket rocker covers (maybe S&S but not sure) in Harley cylinders.
