Need some help trying to find out what year this engine is from:

The guy who sold it said it was a '79 or '80 I6 from another Mustang and said it was a 250 not a 200 as the sticker says.
 
From what i can tell, all Ford's straight sixes from that era looked very similar. Your best bet would be to find the number stamped on the block (above the starter motor on that engine) and find someone who can decipher it and tell you what you've got.

Had a poke around online and found this, i'm sure there's a database somewhere for it online.
 
If it's out of a "79 or 80 Mustang", it's a 200. 85hp of great vengeance and furious anger.

my '82 Ford Taunus had approx that much from a 1.6l/98ci 4-banger.. :lol:
 
My '76 Vega GT had 3hp more from a 2.3l/140ci 4-banger.

Supposedly. According to GM. Buttcrack dyno said 40.
 
If it is a 200c.i. motor it will have 5 freeze core plugs on the side of the block and a casting code of: C5DE-H
 
300 I6? They all look similar though. The only way to know is to rip it all apart and check the casting number on the block.

300 I6's were used primarily in light truck / van applications. Ford also made these engines for industrial and agricultural applications as well. If it is as ghsnu says, that the engine is of '79 or '80 vintage Mustang, then it would be a 3.3 I6 (200 c.i.).

I think MustangManiac is on to something here. ;) There is no need to "rip it all apart". A simple look at the side of the block, and getting the casting # should reveal what you are looking for.

I know that's what they were used for but it's been swapped in so there is always that chance. Looks too small though.

Sometimes castings are on parts of the block you can't see, at least on V8s. Been a while since I even looked at a I6.

Now I know casting is the way to go but I just looked up a 250 and this came up, looks identical (looks are nothing to go by on however)

I know what it is. It's a boat anchor.
 
The 250 was just a stroked 200 so they look nearly identical. You can id the 250 by the low mount starter and it has a six bolt bell housing as it shared the same housing as the 302/351 Windsor V8's.
 
Sorry for the double post, but looking closer at the second picture it appears that you can just make out the starter sitting right under the exhaust manifold. If that is the case then it is a 200cid.

I figured is much. The 300 had it too, because I had a 300 and swapped to a 351w, twice.

Bet you they outlive any engine built today.
 
I'm absolutely impressed by the way you guys can tell different engine variants apart, just from the small details 👍👍

To me, they all look like Mustang engines :guilty:

A true Mustang engine is this:

I hated 6's in them.
 
Got to love the shaker 👍
