Technical Stroking a BB 454 engine to the max?

Discussion in 'The Hokey Ass Message Board' started by 2many projects, Mar 2, 2019.

  1. I have 2 big block long blocks in the garage.
    One is near stock with just a .030 overbore.
    The other is a stroker 489, forged crank, roller Crane cam, a decent engine that needs a little freshening.
    My question is what’s the max I can take a BB 454 out to by traditional boring and stroking before striking water?
    Am I better buying a 502 block or going with an aftermarket block?
    I’d prefer to use up as much as I can of what’s laying around here.
    This will be a street big torque engine ideally.

    I wouldn't go over 60, 30 is better on the street. You could have it sonic checked before you bore it. I've ran early blocks 125 over but that was on a drag car and I figure I was lucky.
