What is a good combo for turning high rpm?
Well.....I think you've asked a very general question. what do you mean by "combo"? I mean.....anybody can read a catalog or call Summit and get a recommendation. Know what I mean? But those guys ain't gonna necessarily tell you what mods to make, and so on. First off, a DAMNED good oiling system is in order. I recommend Guitar Jones' thread found here:

You can use those mods on pretty much anything. What a great guy to share that. He did an awesome job. I have built similar engines in the past. I would add that it is also smart to epoxy screens in ALL of the drain back holes on the heads and block. This keeps small parts from falling into the reciprocating assembly and causing major mayhem. I think Guitar Jones made mention of that in the article. One other thing that you can do to help trap small parts in the event of a valvetrain failure. Expoy some STRONG magnets in the heads adjacent to the rocker stands and shaft as well as the valve springs. Also epoxy some in the intake valley as well. Rare earth magnets work well. As for a "combo" regarding parts choices, I would recommend talking to someone like Indy or Hughes. Just remember, you're gonna have to sift through sales hype to get the info you need. Most companies will automatically try to push a product your way while givin advice. Kinda can't blame um with the economy in the toilet. Hope that's what you were lookin for.
