Hot Rods Pontiac 389 transmission options

  1. I had a 57 GMC bellhousing but I didn't use it. Instead I found a buddy parting out a 59 ambulance and used all the manual trans bellhousing, flywheel etc etc.
    As has been mentioned, none of the 55-60 stick stuff will work behind a 65 engine.....stick with 65-79 B.O.P. [Buick, Olds, Pontiac] bellhousings.....not sure on interchange of 65 and later starters, flywheels, clutch forks etc.
     
  2. Yes and some Olds and Buicks used them also. However it actually isn't a Ford trans. It is a Warner Gear trans. Mostly used in Fords. Pictured is BOP alum bell that I have. Notice the dual trans pattern on the rear of the bell. 8 drilled and tapped holes.There is the usual GM pattern like Muncie & Saginaw ect. pontiac alum bell 001.JPG pontiac alum bell 002.JPG pontiac alum bell 003.JPG have and the Ford type pattern. Also has bump outs for the starter on both sides.

    I have a bellhousing exactly like that out of a 69 GTO.
     
  4. '64 A body (Tempest/GTO) used a block mounted starter, big cars had bellhousing mounted starters. Blocks especially service engines could be drilled . As stated before, all 1965's used a block mounted starter.

    The A body w the block mounted starter vs the full size B body w the bellhousing mounted starter is correct for 1964.
    However, on another (all Pontiac) site, the consensus is that all ( w possibly a very few exceptions) 1964 blocks were drilled & tapped for the block mounted starter regardless of whether used in the A or B body cars.

    I also have that aluminum BOP bell housing. Interesting thing is the left AND right ports for starter: Either side.
    A counter man at a Jeep recycler told me the bell housing was used in Jeeps, with the Warner Gear transmission, hence the optional 'Ford' pattern.
    Mine was in my '27 roadster, joining my 455 Olds to my heavy duty Ford 3 speed top loader: Jeep T150 shift tower and tall cane shifter. All a simple bolt deal.

    I would like to get my hands on one of those optional starter bellhousings. Every car I build has a starter, steering box and header taking up the same space, moving the starter would help a bunch.

  10. That aluminum bell won't let you attach a starter to it. The hump is for clearance only. It probably was Buick part # as well. Pontiac and Olds's starter is on the left. No stick shift modern Caddys.

    Right you are, Mark Yac! As the starter on the 455 Olds was on the left side, (block mounted!) my steering box got moved 'up and back'. ('cowl steering', '65 Mopar box with extended sector) ...and yes, the bell is a 'B-O-P' part, being Buick, Olds, Pont.
