    Default 1964/65 SBB 4 speed information

    When I began to search for information on 1964 small block 4 speed cars I found out how hard it was to not only find parts but even identify what is correct. There is much more information on the later cars. I am by no means an expert and credit most of what I have come to know to Brian Stone on this board. I hope this thread can become a sticky for future reference. If you have information on 1964 four speed cars feel free to add to this. Many of the same parts are used on the 1965 and 1966 small block 4 speed cars as well. To follow will be pictures and descriptions of the items that are unique to the cars.

    Correct aluminum bellhousing. Note close up of casting number by clutch fork opening. I have seen other bellhousings that are designed to fit B.O.P. cars that have a starter mount on both sides. I can not confirm but I have been told they will fit but did not orginally come in these cars.

    Clutch and brake pedal set. Both pedals have the letter M in a circle stamped on the side. I have two sets and have found this on both. Clutch pedal is part number 1363523 correct for 64-66. The rubber bumper that the pedal rests against when the pedal is fully released is part number 1361714 for 64-66

    Correct 4 speed shifters were made by Hurst. GM part number 1362411 for 1964. The handle does not unbolt like the latter ones. The shifter is the flat style and chrome plated with no name or logo. The knobs are round solid black with no shift pattern part number 1358778. The shifter knob and the shift handle end are 3/8" fine thread. The side of the shifter housing will be stamped Hurst Competion Plus Patent Pending. The shifter rods are not threaded.

    One thing I am not clear on is the Z-bar or bellcrank. This is the part that everything rotates off of. It mounts between the frame and the block. The early 64 cars had what I call a three piece design. I have two of the three parts and each end had a rubber boot. The second picture is from the service manuel with the missing items highlighted. The piece I have has 1363411 cast into the middle of the arm on the side that would face the engine. The opposite side has two diamond shaped symbols and TH.

    The second type of Z-bar is a one piece design. I am unclear if this was redesigned as a replacement part, came on later 64 cars or 65 cars. The following pictures are a NOS one I aquired.

    Four speed cars that came with the 300 cid 355 Wildcat (355 ft lbs of torque 250 Horse Power Pack) came equiped with a Rochester 4 jet carb #7024045 . Automatic cars have #7024044

    The drive shaft in four speed cars is a one piece solid shaft. The end will come to a point between the yoke. The automatic car drive shaft is like a tube inside a tube dampened in between. I will try to get a picture showing the automatic vs. the four speed as this is hard to describe.

    If the car was equipped with back up lights (optional in 64) the front light harness has two addtional wires. A back up switch is mounted off of the transmission. If anyone has pictures of the switch and mounting please post.

    The dash harness is the same although the wires used for netural saftey on an automatic car are jumpered.

    The rear axle ratio is most often 3.23

    The steering column came in std or tilt versions unqiue to the four speed.

    If anyone has production number information or any other information please post up. (Update Post #35 in this thread has the production figures) How many board members have one?

    Has anyone seen a Special with a 300/355 4 speed ? I have seen ads but all four speed cars I have seen are Skylarks.

    Thanks for the reply Tom, I know the last few times we talked you were undecided as to what to do to with the car. If you decide to part it out let me know about the 4 speed parts.

    I hope some more will chime in.

    One more note on the shifter handle--it has fine thread on the end for the knob to screw onto--later ones had coarse threads.
    The bracket that mounts the shifter to the tail housing is 3/16" piece of steel bent and then threaded for the shifter to mount to. The newer ones had a stamped piece that was thiner and looks completely different.
    Manual transmission cars had a solid driveshaft tube whereas the automatics had a rubber insert (tube-in-tube) design.
    As for the Z-bar, I got some insite into that years ago from the guy I bought my '64 4-speed car from. He bought it new and it had the 3-piece z-bar design. It was cast and actually broke on him. The replacement was an improvement--the one piece design. Apparantly Buick had problems with the 3-piece design and updated the design and sold the new design as replacement part. My '65 Special that I recently sold still had the original 3-piece design on it when I got it. I found a NOS replacement one in kit form (back in 1994) that I put on my '64 when I restored it, so I put the one off my '64 onto the '65. I still have the original 3-piece one off the '65 in the closet at the house. I also have the broken 3-piece one from my '64 that the original owner kept all those years.
    The one piece design is superior, plus it has more mechanical advantage due to a longer leg, so it is much easier to press the clutch in with it.

    Back in 1980 I bought a 65 Special Deluxe 4 door with four on the floor, no consolette, just a boot. It was a 2bbl motor originally. Floor hump was different. I have pics somewhere. That had the 1 piece z-bar. The GM shifter they switched to early in 65 sucked. Best upgrade I ever made was a Hurst Comp Plus! Rear was 3.23. Driveshaft was solid. She ran 15.80 in the 1/4 and never got to 4th gear.

    Also had a 64 'Lark coupe with 4 speed, consolette, AC, 3.23 rear, but was a 2bbl motor originally also. Now a BBB TH400 car, soon to be a 4 speed BBB car.

    Also, have a family owned 65 'Lark coupe, automatic that is coded as a 4 bbl motor but when I took ownership was a 2bbl. Apparently my grandfather thought the car was too powerful for his teenagers so he sent it back to the dealership and they converted it to a 2 bbl!!! Every piece was correct, even the choke hot air tube, but interestingly the throttle link at the carb was the one with the offset for the wider 4 bbl carb. That car is a treasure of originality - has 44k on it now and has neat things like original ball joints, truck mat, all front end parts, some inspection marks survived, etc. Nice thread. If you need specific pics let me know.

    '65 GS 4-speed stuff is completely different--not one single piece is the same.
    A good point was just brought up--in Jan of '65 when Buick introduced the GS, they switched the regular skylark 4-speed setup over to the same GM shifter, floor hump and boot that was used in the GS--I guess that was all for commonization of parts. The Hurst Comp plus shifter went away in the Buick A-body sometime in Dec. of 1964 (it did return in the late '60s).

    Pat (PGBuick),
    I hope you saved all of those 4 speed parts if you are converting back. Neat to hear of a 65 Special 4dr. with a 4 speed. That has to be a rare bird. Brian sold one several months back but I believe his was a 3 speed orginally. Makes me wonder if there were any 4 speed wagons.

    Brian,
    Glad to see jump in. You probably know more on these cars than anyone. Can you give any details or pictures on the impossible to find shifter boots and rings, or back up light switch and mounting?

    Has anyone found any way to distinguish these cars short of a build sheet or orginal paper work. I havent found any thing on the cowl tag or vin that will identify a car as a 4spd.
