Engine ID
 

Probably barking up the wrong tree, but is there any way of identifying an engine that still has all the equipment installed and in the vehicle, other than checking the VIN number?

Re: Engine ID
 

what do you mean by 'identify' the engine? Are you referring to the engine class, bore, and stroke size? Or to the exact RPO production code associated with that engine?

Wanting to identify as a 305 or 350.

Always a way. Just involves a little looking in the right places.
Look on the link.
You’ll find number locations pics and what the numbers mean.
Some numbers like casting code are a little hard to see but with the right tools you’ll see them.

I don't know what year they started, but some blocks have it marked on the drivers side rear upper surface. This is marked 5.7.

I like to reference the block stamping at the front passenger side where head and block meet. The 2-3 digit letter code is a good indication of size and application - recommend use this site for ref pics, and about 3/4 of the way down the page is the index for the letter codes that you can click on to see what yours is. https://www.nastyz28.com/chevy-engin...-stampings.php

Thanks fellow members. You have given me plenty info to move forward. Appreciate it.

Re: Engine ID
 

5.7 would be a 350, correct?

Re: Engine ID
 

Yes. There's 61.02 cubic inches in a liter. There's some rounding involved, since the actual displacement of a 350 is 349.67 cubic inches, or 5.72 liters.
