Rebuild on a 371
I have a 1957 Oldsmobile 98 with a 371 in it. It only has 28000 miles on the motor and has been sitting in a garage for 30 years . I pulled the motor and started taking the motor apart. The motor was locked up , I have all the pistons out but one that looks to be stuck. I think I am why over my head on this and was wondering if I took it to a shop what do you think it would cost to rebuild it.. Thanks and Hope all you Oldsmobile owners have a great Holiday

Before disassembling a weather stuck motor, you should get all water off of the top of the pistons if there is any, and fill the spark plug holes full of trans fluid and let it sit. Eventually, the rust and varnish will break up and you can turn it.

Thanks , But I did soak it all in tranny fluid and even tried blaster , I let it set for about a month and it still wont move. I even flipped the motor over on the stand and tried soaking it from the bottom.. Still no luck

Wow.
Sledge hammer?
I seized a rod bearing so bad once that I had to use a sledge hammer on the counterweights to turn the rotating assembly.
Believe it or not, I gave the mangled mess to Steve-o on here, and he runs 9.40's with my old block. Happy ending to that motor's life story.

J is correct. Automatic transmission fluid or diesel fuel will usually unsieze a frozen engine. If you contact Ross Racing I am sure they can help if they know their stuff. You should be able to get engine internals from Kanter. Unfortunately, aftermarket parts for the early Olds engines are scarce.
FWIW, I just rebuilt my 455 last year and I spent about $3000 on all of the machine work and aftermarket parts I bought. I bought an aftermarket intake, HEI distributor, camshaft, oil pan, rocker arms, and timing chain.

I have stock and speed parts for the early Olds family
as well as trans adaptors auto and stick
we are devoloping new stuff all time
I've got enough new items that you can build an early Olds using just the
bare block and a few odds and ends
and I also do restoration type blueprinted engines and everything in between

That is AWSOME Tony! Too bad I didn't have the means years ago to trick out my 1964 Olds 98 with a 394. I did some engine work to it and drove it through college but ended up selling it last year because it was just too far gone. Those early Olds engines are cool!
They even make valve covers for SBC engines that emulate the older Olds engines (I think the 303)!
