I understand how to break down a casting number for example, I know C8ZE-9425-A is a 1968 Mustang manifold with revision A but how do I determine what size engine it's from or if it's a hi-po part or standard?

Google. A lot of that is specified in books and in brains of old timers. Much of it is speculation and possibly witchcraft.

You will find odd and mismatched parts from 1968. It was a transition year, from 289 to 302. Both were made that year, and it isn't uncommon to find either one with parts that "should" be on the other.

If the engine has hi-po heads on it, it should be obvious with the valve covers off. They have screw in studs and spring cups cast into the heads.

Here are the numbers for several factory cylinder heads:

Thanks guys.  I'm not looking to identify heads right now but I was just asking the question how to identify what the parts actually fit on.  Like the intake I referenced - is it for a 289 or a 390 or??????  Same question for some exhaust manifolds I have.  Every reference I can find only gives a range of numbers without identifying any specific application.  In the case of the intake it's 9421-9499.  Ok, what does manifold 9421 go on?  It seems that information should be available somewhere.  I have googled my butt off trying to find that list and have not been able to.

289 or 390?

Thats Windsor or FE. Should be obvious just by looking at it. Other than being Ford V8s, they look nothing alike.

Someone just turned me on to the Mustang Tek website which has just what I was looking for.

http://www.mustangtek.com

Turns out the manifold is a '68 Mustang/Cougar 302 J code 4 BBL.

Thanks for your comments.
