    a stock good steel crank will take around 500 hsprw with a 4 blt sbc,
    more power or a motor taking abuse, bjuice is right u can get a
    good forged crank for around $600. bucks, competition products has
    cola close outs for around $500 bucks for sbc :?

    i probably should have just said this yesterday but didn't...so hear goes..

    My opinon is this...there are some places to cut back on a motor...but i would stay with the best parts when it comes to rotating assembly,,crank,rods,piston's.....this makes up the core of your motor..by spending a little more money and getting best parts it will open up the door for you down the road..longivity being #1...

    i have never MET one person that built a motor or car that DID NOT want to go faster etc...Do not make that mistake and tell yourself you will be satisfied,,cause you WILL NOT.....YOU WILL want more..SPEED/POWER is addictive..its more addictive than drugs to some of us..(hint,hint)...
    so do yourself a hug favor and build a solid bottom end,,so you can throw a little shot of spray on there, or make a cam or head change for some more ponies and not over rate your bottom end..

    my opinion.

    Both crankshafts you mention start their life as a chinese forging but are heat treated and manchined in the USA. It's hard to find an american forged and machined crank for less than $800.00 to $1200.00. As mentioned the cola cranks are American.
    But as BJ says build the short blk. to the best that your budget will allow and in the end you'll be happier.
