    An engine swap is in the plans for the Hudson this winter, going to pull out the SBC and thinkin' about replacing it with either a 324 or a 394 Olds. They are a little heavier and the car only weighs a touch over 2600 lbs. Anyone have any tips/tricks on putting either one of those motors in a coupe? Are they too heavy? Also have to take into consideration the lack of parts availability over the counter as I drive it a lot. Would also have to change the diff, I have a limited slip 87 Camaro diff in it now, that aint gonna cut it! What da ya think?

    The 324 with the 3 spd manual trans that would get changed over to an automatic.

    Or a 394 and auto trans similar to this.

    That 394 sounds like a good swap. No substitute for inches and torque.
    Unless you hang some giant tires out back the rear will likely hold for a while.
    Be sure to take pics!

    I vote for the 394. Maybe a late 50s olds or pont rear to go with it. "Shades of gassers past"!

    :p

    I don't know if it's a problem with your coupe but the 324 that
    I am putting in my '40 Ford coupe had starter/steering box
    interference problems and I had to use a kind of rare starter
    change-over aluminum lower bell housing half that moves the
    starter to the passenger side. I have a spare one that's new.
    If you need one,PM me.I also have the complete '56 Olds Hydramatic setup,trans. and flywheel if you need it.

    Just my 2 cents; I'd go 324 stick. Alum intake would save a small bit of weight.

    I'd check with Goatroaper02 to see if he has what it takes to put a chev trans to that bell if you don't like the selector type 3sp. The chev input is too short but maybe he has a adapter pilot bushing or something..

    It's not to hard to make a shifter for the Olds trans, but will have a backward shift pattern.

    I've been told that it is possible to put a newer 4 speed hydromatic behind the 324 so I'm gonna do some checking into that. Either way I decide to go it's gonna me an automatic tranny, I drove truck for 26 years and the last thing I want to do is shift another friggin' gear! AARRGGGGGG!!!!!:mad::D:D I would really like to run an aluminum multi carb intake with Fish carbs on it.
