543 ?

I'm sure a combo like that is workable for some class out there, but have you had anymore thoughts on what classes you'd like to run? You did disclose your intended budget in the other thread, and even though you intend to build "in house", i'd rule out Comp Eliminator. With the costs of constantly keeping up with running under the indexes, and the travel involved to get to races where you can run that class, your talking 6 figures to be really competitive. Think of it as, Pro Stock lite.

Bottom line is, I'd hate to see you spend that kind of money on a tube frame car with a expensive engine, only to have no place to run it other then a fast local bracket program somewhere.....unless you're comfortable with that? Just make sure you thoroughly research what the best type of racing the build will fit into before you start you're program.
