Could do, but it's a relatively tiny improvement and there's an HRC '28 flywheel which is smaller and lighter than anything else anyway.
And I like the PGMIV

My bike dyno'd at 9 horse lower than it has in the past, that's just wear and tear, anything up around the 65 bhp mark would be good and about a 25% improvement on what I've got now. That's only 3 bhp more than it's made in the past.
I think there's a line to draw between power and longevity and (of course) what I can actually use, Dan (Gecko Racing)'s '28 absolutely flys, it's probably the fastest thing out there but even when it does stay togeather it's going to want a rebuild after a trackday or meet.

+ all RS stuff except the cases is legal in F250 if you want to spend a fortune on engines and maintainence.

And either are a rather boring know to work route.
I know of a source for good copies of the HRC '28 ram air box, there's VHM heads to try as well as different fuels, 010 (and other) cards etc. I'd rather have a play with that sort of stuff.

I think keep the porting fairly stock, try and keep ring life nice and long so I can get plenty of practice in without worrying about it.
