Just got the 64 394 ci Olds engine installed in my 50 Olds 98. used the stock 50 olds 4 speed hydro and the 50 olds flywheel(after having the 64 engine internally balanced as thats how the 50 olds flywheel's original engine was balanced back in 1950). anyway, on start up, the tranny pucked bunch of ATF. Rather than pull the hydro again, took the old girl to local tranny shop, they pulled the tranny and they feel the current setup isn't allowing the torque converter to insert far enough back into the tranny to seal. Anybody out there used a 57 up 371 or 394 olds in front of a 49 to 51 olds four speed hydro? This is the same setup that Stone/Woods/Cook used on their B&M hydros to power their 41 willys coupes in the 50's and early 60's so there has to be a solution. Thanks for any help. mike

Re: NON CORVETTE TECHNICAL QUESTION
Don't have any information on this technical issue, but I have heard the song about "My Rockett 88". When was the Olds Rocket 88 available? -
Re: NON CORVETTE TECHNICAL QUESTION
There was a "Super 88", "Rocket 88" and "Delta 88" available from Olds, thru the Sixties. There was also the deluxe Olds 98. Good old memories.Comment

Re: NON CORVETTE TECHNICAL QUESTION
Mike the torque Convertor didn't cause the tyranny to throw up or burp , but trapped AIR in the pick up passage . I did some thing like you did once before and I just added a steel square block 1x1x1/2 in. and longer bolts to move the TC back towards the trans. Worked great and had no problem at all. Just use the same weight blocks. Oh! by the way Olds are my favorite car of all in the 50's. I had a 55, 98 Convertible. PS: you can do this with out pulling the trans. OLD MAN!!! Merry XmasComment

Re: NON CORVETTE TECHNICAL QUESTION
Roy: on a 50 olds hydro, the factory used a paper gasket between the torque converter and the flywheel as there is ATF in contact with the flywheel inboard of the attaching points of the torque converter to flywheel. If you are suggesting i add a shim between the TC and Flywheel, it would have to be 5/8" thick and be 360 degrees with a circumferance equal top that of the torq. conv.. is that what you did previously. What kind of tranny were you dealing with? This puppy uses 32 bolts to attach the TCX to the flywheel. regards. mikeComment

Re: NON CORVETTE TECHNICAL QUESTION
Mike, check the depth of the inset into the crank on the 394, relative to the length of the nose on the trans. Post-56 olds engines were not drilled to the same depth as the early engines to accomodate the nose of the torus assembly for the fluid coupling (not torque converter).Bill Clupper #618Comment

Re: NON CORVETTE TECHNICAL QUESTION
First year for the rocket V 8 olds, aka kettering engine, was 1949. had 303 ci and about 140 hp(compared to a 90 hp 216 chevy 6 banger of 49)The 303, in the 88 bodies, were NASCAR competative. the 88 Olds body was very similiar to the 49 chevy and pontiac bodies( doors and all glass would interchange) the 98 old bodies were very similiar to the Cadillac bodies of the same year and a eindshield from a 50 Olds 98 will fit a 50 coupe de ville. I cut my teeth of Caddy 331 ci's and the olds 371 and 394 ci's. lots of torque but unable to rev with the small block chevys of the late 50's and early 60's. Too bad GM is ****-canning the Olds division. mikeComment

Re: NON CORVETTE TECHNICAL QUESTION
clup:i had the '64 394 crank drilled for the pilot bushing that was used in the 50 olds but not in the 394s ( and probably not in the 371 either(unless the crank was a standard shift olds) BTW, the 50 olds pilot bushing is identical to that used in the mouse and rat chevy motors. I wasn't aware the chevy and olds were identical till the NOS 20 dollar 50 olds bushing arrived from Fusick. I installed the bushing in the 64 crank before i mated the 50 tranny and the 64 394. Could the 64 crankshaft flange be situated 5/8' more aft than the 303 crank flange? hate to tear the car apart again to check that possibility. thank and super holidays to you and val. mikeComment

Re: NON CORVETTE TECHNICAL QUESTION
It sounds like your torque Convertor and fly wheel are the same???
Yes I was talking about adding a spacer between them, but you cant???
Then where the fly wheel bolt to the engine crank can you add a thicker made up plate between them and use longer crank bolts?????Comment

Re: NON CORVETTE TECHNICAL QUESTION
Mike,
Old racing huh! I'll bet that you remember Coleman-Taylor in Memphis Tenn. That was Coleman-Taylor Transmission if you recall. They are still in business and probably have had as much experience on the Olds as anyone in the country.
Don't have the number but it is area code 901. When you reach one of the stores ask for Bobby Anderson. If he is still alive and working he can answer your question. Probably someone else can also answer the question.
Good luck,

Re: NON CORVETTE TECHNICAL QUESTION
If I remember correctly, something changed in regards to crank/torque converter/tranny about 55-56-57. Also, the last year for the 4sp hydro (as I recall) was 60. Since you have a 64 crank, I'm thinking you may need to use whatever changed in the mid-50s thru 1960. My dad was an Olds man, but unfortunately cancer, took him in 65 just after I got home from Nam. I can only remember some of the things about hipo Olds setups that he explained to me.
By the way, do you just happen to have a J2 setup that you plan to install? That would be a neat addition.Comment

Re: NON CORVETTE TECHNICAL QUESTION
Mike:
Back in the old days before I could afford a Corvette,I played with a 1950 Olds 88 hardtop. I slid in a 57 371 bored to 394 Isky cam.J-2.Bolted right up with just a new pilot bushing. I used a 1955 hydro that had a few changes from the 50. Modified it so I could hold in 1st gear if I wanted. I still have the books and tools for the hydro.
It does not seem likly that the converter is not in the front pump far enough, unless converter is possibly defective and leaking at the hub.Or the leak is elswhere?
I believe Olds,Pont and cad used interchangable hydros except for minor differences. I have not worked on one for a long time,should have interchange info to.
Good Luck

Re: NON CORVETTE TECHNICAL QUESTION
Mike, Roy
Roy's idea about a spacer between the flywheel and the crank would provide less rotational mass and would be easier to balance. (more or less a crank extension)
This would need to be a precision machined piece with close tolerance interface surfaces that duplicate both the flywheel and the crank mate locations. You would also need close tolerance bolt holes and longer bolts of the correct temper.
Not a cake wake, but I believe a sound candidate for a solution IF you can resolve the starter / flywheel engagement problem that will result.
