Im tryin to figure out what what size engine my buddy has in his falcon while hes gone, hes not sure whether its a 289 or a 302, and Im lookin under the hood and cant seem to find anything, I know the casting code is under the starter buts that a real pain to get to right now,
it has 8e27 on the left head under the valve cover and 7d16 under the right, both have wc with a p under it stamped on both also if that helps, thanks alot guys
Well those should be date codes for when the heads were cast. And that won't tell you what you want to know. You need to crawl under the beast and check the side of the block IIRC right behind the starter I think. But you already knew that right? Be advised depending on the year it could also be a 260. Once you have the casting number from the side of the block run a google search and you will find out more than enough on the engine. B
Post a pic of the top of the block BEHIND the intake manifold, and I will tell you what block you have; otherwise, the ONLY way to know for sure is to check the markings on the crank, or measure the stroke of a cylinder with the head removed.
That thin flat strip of engine metal is what he's looking for, between the intake and trans bell housing. Are there any numbers stamped there? If I remember correctly there were no numbers from '65-'67 (except Shelby's) and from '68> they stamped the VIN there, which would make it a 302 most often (289's were used in some '68's to finish off stock).
Pic below are the 2 sets of numbers you're looking for that are under the starter, you'll probably need a toothbrush, rag and gunk to get it clean enough to read. The short set of numbers is the cast date, the long one is the casting #. Casting number start of C7, C8 would be '67, '68.

Kind of sounds like it is a swapped in motor that has been apart or at least different heads based on those casting dates. Don't think you will find them a year apart. Only sure way is as Al mentions.
I scraped off the metal part where you mentioned and there were no markings, probably a swap then? Ill try and get the other markings soon, that side of the car is up next to the curb so its a pain to get to

The marking they are talking about are usually not really distinct markings, not cast in but stamped. The number by the starter will tell you what the motor was cast as, most likely a 302. Just wondering why you really need to know for your friend? Lots of the parts are interchable between a 289 & 302.
