    \'77 or \'98 block????????

    When I decide to do the stroker thing, which block should I use? Both are 4 bolt mains and neither of them have been bored. I've been told that the older blocks were made stronger, but I also believe in the new technology of making things better. What do you all think? /forums/images/graemlins/ears.gif
    Thanks in advance... /forums/images/graemlins/thumb.gif

    If you want a roller cam, go with the newer block.

    Otherwise it matters not much.

    Crappy castings can be had from either year....

    Yeah I say go with the newer block for roller cam, just remember the flexplate or flywheel will be different.

    From what I've seen on my vortec heads, the castings are probably MUCH cleaner in the newer blocks, but the only real advantage to that being perhaps better oil drainback.

    I'm a big fan of roller cams, and factory roller cam blocks are IMO your best bet to go "cheap" roller.

    Go for the new block. Cheap roller cam (as already mentioned. Probably much less clearancing necessary for the stroker crank - my buddy's crank fit without fuss... although he did grind extra just to be extra safe.

    One-piece rear main seal is a very nice benefit. /forums/images/graemlins/wink.gif
