    What are the engine-blower specifications?
    How much power are you planning on making?

    How many of you are running harmonic dampners on your blown alky motors?

    Was it Lunati that used to put harmonic dampning material in the counterweights of there crank?

    I'll second that, RCD has been good to us.

    We run all of there drive stuff, NO balancer, just a crank hub, we dont run a crank support either, front main always looks good. Numbers 2 and 4 are scuffed usually, I was told its a crank problem.

    Run a ATI Blower dampener no support @ 20 psi no problems here. Make over 1300 hp on a stock block BBC.
