    BBC vs SBC timing chains, interchangeable?

     



    I was shopping for a timing chain for my 454 and came across a few where they said it would fit both big block and small block. TRUE?

    no $h!+...???
    Why does almost every catalog list them as different part numbers...?
    The kicker is the price differences, BB is almost always more expensive...
    I will just order a sbc one, that is, unless someone else here has more info on this topic

    There might be a clue in that statement. The chain may be the same, but are the gears? For a $50.00 part, why not order the one you KNOW will fit?

    ooops, I should have clarified. I was asking if the set was the same. I guess the chain could be the same but the gears could be different. I am on a budget, so if I can save $20 or buy the next level of quality up for the same price, just by ordering a SBC as opposed to a BBC (if they are identical), I am going to do it.

    I guess Pat answered that, the gears are diff, the chain may be the same...
    thx guys

    Since it is a cheap piece, I was going to buy a double roller...Am I wasting my money? I haven't seen one for under $40. Should I just buy a stock replacement?

    It depends on if your going to drive like grandpa to the store, and around town or not. If your going to jump on it once in awhile, get the true roller chain and gears. If you buy the cheap one, you will probably be doing the job over. You would be money ahead to just get the good set to start with.

    I think you need to look around. I think you can get a Cloyes DBL roller CHain from Powerhouse, PAW etc for twenty something bucks. If your not gonna build this motor again any time soon, and your gonna beat on it...Id say the extra few bucks for a DBL roller CHain is worth it. From my expereince which is limited compared to tohers on here like Pat, Erik etc...the first thing that goes on a Small of big block chevrolet in the cam, lifters and timing chain...for the extra 10 -15 over stock Id get the dbl roller.
