    Nope. Change the pistons.
    3.25 stroke compared to 3.48 cretes a different compression height at the piston.
    "APPROXIAMATELY" an eigth inch.
    What if the "Hokey Pokey" is what it's really all about?

    change the crank

     



    why would you de-stroke a 350? get yourself a 350 crank.

    if you are looking for a 327 ci motor, using a 327 crank will require oversized bearings, or bearing spacers to make up for the bore diff.
    the 350 has a larger crank main than the 327 did. and you will need the 327 pistons too of course.

    1968-69 327's were large journal cranks the small journal was 62-67.A long time ago I saw the Bill "Grumpy" Jenkins book in the late 70's and thought building a 331 would be a cool build,I used a 350 4 bolt block and a '69 large jounal crank and the TRW domed pistons for a 327 365HP Vette.It looked like the engine on the cover when I finished it,Damn BAD motor and wicked fast!

    Sorry Bruce, but you got it backwards---the 350 crank will put the 327 piston out of the hole 1/8 inch

    however , you have it correct for what the op said----327 crank, 359 pistons
