    Hey there folks. I have a 73 with a 383, 3 speed with 1500 miles on the engine. Drove it for about a month and really hated the gearing which resulted in me moving on to another project. I have a 2 part question

    1) Its been sitting idle for a year (yes I know bad on me), I want to get it up and running. Before I try to turn it over, whats the recommendations to do before starting it

    2) Once I get it started, I plan on taking it in to get the gearing sorted. I want to cruise and at 65 mph its just to tached out. Love the first gear but 3rd is running to hard at 65 mph. What gearing is recommended for the 3 speed muncie for causing?


    Thanks
    Newbie in Texas

    Mine has sat for a year inside a garage, I just cranked it up and went. This was before ethanol fuel though, so you might want to drain and install fresh fuel, check all fluid levels before cranking.

    I assuming you have a 3 speed automatic transmission like a TH350/400? I recently installed a 700-R4 overdrive transmission and the only question I have about the install is why I didn't do it earlier. Made it seem like an entirely different car - for the good. IMHO

    BTW - welcome to NastyZ. :)

    Thanks for the quick response. I am just not ready to swap transmissions yet, still feeling the "man I bought a really expensive engine and my wife is still mad" phase of my ownership, and was hoping to defer the transmission swap for gears to start....

    It might be just as easy to switch to a 4 speed Muncie.

    I'd change the rear gears first befor anything else, cheaper to do. A 3 speed manual? Did the thing have a column shift on it?

    It had a column shift that I switched to a floor shift, 3 speed automatic.

    Still a 1 to 1 final drive ratio. Gear swap will probably be the cheapest but depending on what all is needed, the OD transmission may be the way. Do you know exactly which transmission you have now a what's the gear ratio? Most street 383's are heavy on the torque side and can use numerically lower gear ratios.

    Then you have a TH350 or TH400 for the trans. When I had a TH350 in mine with 3.42's in the rear my rpm's at 70 mph were 3100-3300. Don't know what gears you have but the way to go is with an OD auto trans. If your gonna abuse the shit out of it get a 4L80E.Of you drive it like a normal person would with a little crazy stuff a 200R4 or 700r4 will do.
    I have a 700R4. I'll admit that going to a OD trans made a big difference in drivability.
