Ok, here is the problem.
I'm on my second attempt to get a rope type rear main seal to hold. I haven't gotten anything to last longer than a month at best . I would like to replace it with a neoprene seal out of a Ford Y block or some other small block Ford conversion I have heard of in the past. But unfortunaly, I can't find that thread in the search engine any more. I need that part number or at least the size and kind of motor that part will convert and work in a 324 engine. As you probably know , this is a major undertaking in a 55 Olds with an automatic transmission. You have to pull the engine and transmission because of lack of room between the pan and that monster X frame. I want this to be my last attempt on this car. If you have any knowedge about this conversion, could use your help..... Tedd

Found this after some searching.
A rubber alternative to the rope rear main seal found in all GM (Oldsmobile) V8 engines can be made from the rubber rear main seal designed for Chrysler (AMC) 3.2L-4.2L (199-258 CID) engines and the seal designed for the Ford Motor Company 7.0L-7.5L (429-460 CID) engines.
McCord Gasket Corporation engineers report that the rubber seal for the Chrysler (AMC) 6 cylinder engine can be used in several GM Oldsmobile V8 engines by trimming off the tabs on the upper half of the AMC seal (see illustration below).
When modified, both halves of the AMC seal will be equal and will properly fit in the seal cavity of the Oldsmobile blocks. The AMC seal will fit Oldsmobile-built 4.3L, 5.0L and 5.7L (260, 307 and 350 CID) engines (gas only) once the seal has been modified.
The Ford 7.0L-7.5L (429-460 CID) engine seal will fit the 6.6L (400, 425, 455 CID gas) and 5.7L (350N CID) (diesel) engines with no modifications necessary to the seal.

I wont say this info is WRONG in giant letters only that it is useless for the 324 engine. There appears to be a 2 piece rubber seal available on Ebay for your engine that may be better and easier to install than the factory rope type. I think there may be a neoprene seal for your engine somewhere but I do not know the source at this time.

Hi Ted,
I tried the 429 rear main out in a 394 and had to machine up a holding sleeve to make up the differance,it worked for about 10 years and is now leaking.
The BEST GASKET rear main is now available and is the route to go,this is on my list for all of my cars ,I was quoted 40.00 bucks a copy and think this is a good price.
