454ci Engine RPO code
Can anyone tell me where to find the RPO codes or how to get information about this 454ci engine? The RPO code in the engine compartment on the factory sticker is 1LF8. It is in a 1974 C-20 truck. I am also interested in finding out what the rear end gear ratio is, and the RPO code is 1G80? Is there a code or how do I figure it out?
