I am going to start looking fo a OLDS 455 engine. How can I make sure the block, and the rest of the parts are correct ? :confused:

Thanks

455 Olds blocks have numbers above the water pump, they all end in the letter F. The casting numbers on the heads tell you the year, A-J, from 68-70's. For codes and additional info try 442.com, the tech pages are very helpful.

Just look for a 80's model jet boat and you'l probably find one.

Funny, because Olds build their last 455 in 1976.

Go to 442.com and go to the FAQs. You'll find more than you ever wanted to know on casting numbers, bore and stroke combos, and HP numbers.
