I have a 1967 Olds 98 convertible and looking to sell it but not quite sure which engine size it has to get a good value on it and to represent it correctly in my ad. I've looked a little but haven't seen anything that jumped out at me. Any help would be greatly appreciated.

Thanks,

Tom

 

I think it is a 425 (if it is original)

 

Look on the front of the block, on top of where the water pump bolts on.
389244D, is a 425 cubic inch engine
38917-1, is a 330 cubic inch
381917A, is a 330 cubic inch
390925E, is a 400 cubic inch
394417-3, is a 330 cubic inch
395558-2, is a 350 cubic inch

Hope that helps!!

 

Thanks! That should help a lot...was always looking for the secret decoder ring. I'll run over to my garage and take a look.

 

Welcome to CO, let us know what engine you have in there.

 

Welcome aboard

Glad you joined up

 

It is the 425. The code on the front of the engine matched the first one on the list.
