    Hello all,
    i just joined up and have an engine and trans. that i do not know if they are compatible. i've got the chance to buy a 1965 283 high torque V8 that originally had a 3 speed manual and i want to know if a later TH 350 trans and flex plate will bolt up. Mainly don't know if the flex plate bolt pattern will match the 283 crank bolt pattern.

    Anyone got a thought for me on this?

    Thanks, 71 Longbed

    I'm almost sure it will considering the production of the 350 Turbo began in 63 or 64. If the flex plate doesn't match for either of them, then there are plenty of companies that make conversion kits for it to work.

    It will work just fine. You just have to make sure your flexplate will match the starter and torque convertor bolt pattern. Flexplates are cheap and easy to find. Just make sure the flexplate is for an 85 down engine. 86 went to one piece rear seal.

    Yep it'll match up.
    When it came to GM small blocks they made them compatable with almost everything.
    Many 283's came with the 2 spd auto which was a great drag racing trans, but for those that were doing more street cruising the swap to a TH350 was the popular way to go.
    I've even seen a 700R4 behind a 283 in "T" bucket.

    Thanks a bunch i appreciate your input. Yeah, this Chevy stuff is new to me... I'm a Pontiac nut (big Catalina's with 4 speeds) got 3 of them and this '71 C10 is my recently aquired daily driver, so now, i'm making this one my own with mods etc. I'll post pics here pretty soon.

    Thanks again.
