Ok so I'm looking @ an engine for my 76 regal but I'm having a problem identifying it it's in a 74 Electra 225 and I know they come standard in those call but it looks rather small to me also I'm having a problem attaching the file to this message any help will be well appreciated thanks in advance
455 is cast into the block right behind where the intake manifold mates. Use a flashlight and you will see it.
455 valve covers have 5 hold down bolts 2 on bottom, 3 on top and water pumps are completely different looking
