    Here is where I got side tracked on the 4 speed swap. I knew it was going to happen, it was just to close to pulling the motor during the swap since quite a few items were already removed or loose.

    It started out as a exercise to take a look inside, check bearing clearances, add notched pistons and a 107 cam and clean everything up again under the hood.

    But quite a bit of #3 cam bearing shrapnel was found on the windage tray and in the sump of the oil pan.

    Awaiting parts as we speak.

    Man..... Kinda tragic to hear Greg!! Oh well i am sure you will have it back together.

    While on the subject of your car I have a question. Did you run your car before the switch over to manual at a track and after? Were you able to gage if the manual swap improved or hurt your 1/4 mile times?

    I know Automatics are usually more consistent but less fun IMO but in some cases it makes a big difference (well so I have been told) since you have a more versitle control on your launches.

    Woodie, the only dimple is where it passes near the steering shaft. Is this the one you are referring to? I will look them over in case I have forgotten any and take pics if you like.

    Pete, No, I slid the tranny in and then right back out. Didnt want to have to do any more repeat disassembly than necessary, my mind was pretty made up to pull the motor. All the guys at work were like your crazy, etc...Looks like I get the last laugh. Well kinda

    My combination was mismatched in the convertor selection. It flashed 4200RPM immediately and shifting at 5500-5700RPM it just zoomed me almost out of my 118 cam powerband and just a short band before shifting. This plus the undersized 750CFM Holley model 4150 dbl pumper my car wasnt at its full potential. So I have no doubt that the 4 speed would have been quicker than with my old converter.

    I guess I will never know exactly how much though. But I do know it will be much quicker when I am done

    Looks like the machinest and the parts availability will determine when this summer she will be back on the road. Do you like that postiitve thinking

    The culprit, There was a lot more shrapnel on the bearings before I pulled the cam out. Every bearing is damaged, I only thought 3 and 4 were before. Here is a hunk of shrapnel just waitng to tear off.

    staged67gspwr I am using the Dave Kleiner Repro'd fork and adjusting rod along with the T.O. bearing from the Centerforce Clutch kit.

    sparkplug The chevy pedals are different, Chevy used a much different upper rod that turns into the pedal 180 degrees from the Buick method. There was some excellent threads with comparison pics on this, not sure if they survived the last site crash. The Buick and Olds pedals I have seen are the same.

    Exclamation

    On a 70 to 72 car, the neutral safety switch is mounted to the bracket that the pedals mount to. The purple wires go to the switch with an extension harness, which is being reproduced.

    The back up light switch mounts to the top of the steering column about 6" from the firewall. The green wires plug in the switch, which is activated by a linkage from the transmission to a frame bracket to the steering column.

    Good news: the back up light switch is reproduced by M&H for $29

    Bad news: the neutral safety switch is hard to find.

    On the 66-69 cars, I don't know if they are the same as 70-72

    Thanks

    No, I did not. Just use the correct bolts with the lockwashers. and a torque wrench. Good luck.

    No, I don't remember having to do that. I believe that mine was more rearward anyway. Of course, I did the job back in 1992, so the memory isn't exactly "sharp"!

    A turbo 350 to Muncie swap did not require moving the crossmember.

    I do not know about the turbo 400 location.

    Here is a pic of the Buick shifter and linkage (70 -72 vintage).
    Where did you get the "bolt on" Hurst shift handle? I have a short one now and Dave told me he was reproducing this and I've nothing since, AL.

    Default Re: Operation 4 Speed Is Underway

    I currently have a fresh 350 in my 71, had the motor balanced with the flexplate. I am planning a conversion. Is this true: I read that if you put the manual flywheel on, you will screw up the balance and kill the botton end with vibration?? Any truth, because if that's the case, it'll scare the hell out of me.??

    Default Re: Operation 4 Speed Is Underway

    I can only speak for myself, but I just bolted the flywheel on. My 400 was balanced to the flexplate also, but I have not noticed any vibration. The flywheel itself should be balanced when you buy it. I got my from TA Performance.
