    PN# 424-4250-DC6F-6385
    It's for a 6.385 rod. If you need one for 6.135 rod I can get you one at the same price.

    I have personally used them 1500hp blown motors before with no problems and that is a small block without a crank support.

    High performance aftermarket Cranks don't really HP have ratings. The hp ratings you see are made up cover numbers that other company's use like Eagle, Scat, etc.
    You may want to call Molnar for the detailed information.

    Molnar makes good stuff and Tom Molnar is the nicest guy you would ever want to talk to. He has probably forgotten more stuff than a lot of other guys will ever know. It is true that there is no official crankshaft horsepower rating system and the companies that are rating them like; Eagle, Scat, etc. Are making these numbers up. I would feel very comfortable running a Molnar crank with a motor that has up to 1500 hp.

    Are they American Forgings or are the forged overseas?

    I thought there were rules about commercial sales in the spam forum.

    Can't blame a guy for asking. Being that the site touts being a great crank designer, you never know since it doesn't state it. I can get an American Howards crank for $700. I just can't get it in the 4.25 which is the size I need for a friends engine.

    They are forged overseas but machined in the US (Michigan).
