Gen 3 Coyote in 05-09 GT

I believe the gasket needs to match the heads

Head gasket needs to be no smaller than the bore.

Ok so we have one for the gen 3 and 1 for the gen 1…..any tie breakers??

The Gen 3 engine has a slightly larger cylinder bore than Gen 1/2. This accounts for the extra displacement.

I’d do more research but from what I remember when guys doing 3-2-1 builds, you match the head gaskets to the heads for their oil port. The actual cylinder sealing surface ring is always larger Than the cylinder bore itself

From what I see from other online sources, Matt James is correct. The gasket must match the head. The people who have done the gen 3 block with the gen 1 or gen2 heads have not mentioned any issues when using the correct head gasket for the heads. I hope this 100% true because I just ordered a short block from my local ford dealer this morning. They price matched the price from Tasca, which was the most reasonably priced dealer I found and I don’t have to worry about shipping charges. For whatever reason, Tasca wanted $1100+ to ship to my location. I have had full engines shipped cheaper than that so I’m not sure why it was so high.

The only heads that are compatible with Gen 3 blocks are Gen 3 heads plus '11-'12 Gen 1 heads (including '12-'13 Boss 302) that use long 12mm head bolts.
The '13-'17 MY heads use shorter 11mm head bolts and are only compatible with '13-'17 MY blocks.
If you're using a Gen 1 Mustang PCM for a Coyote swap into an '05-'09 Mustang (V6 or GT), your swap engine will need to have the Gen 1 camshaft drive system (timing set). This means you'd probably also need Gen 1 camshafts and Gen 1 heads. If you want to bolt these items onto a later generation short block, the '11-'12 items will only go onto a Gen 3 and the '13-'14 items will only go onto a Gen 2.

Thank you Dino. I bought a first gen coyote engine for parts and I will be using the 11-14 pcm. I have the first gen cams and stuff and I am going to put new gen 1 timing components on it when I assemble them. I believe I have an 11-12 engine due to the block having the piston oil squirters but I have been unable to nail down exactly the year. I have tried looking up the head castings and I have been unsuccessful. I will measure the bolts but is there a place that spells out the head casting and where I can find it? I’m 99% sure it’s an 11-12, but I’d like to be certain. The short block I will be using is a new gen 3 from Ford. The block from the gen 1 was scarred and needed rebuilt and I found it cheaper to buy a new one. Any help is appreciated.

I don't know if you got this build done or not but I have since released a plug and play swap harness to utilize the 11-14 Coyote ECU in your 05-09 car and have everything work including the speedo gages, ac and cruise. Link it my signature!

Wow, a lot has changed since that post! That engine turned out to be complete garbage and I’ve since purchased a new gen 3 block, gen 2 heads, and I’m gathering the gen 1 timing components. I was extremely excited when I seen you released the wiring harness and that is on my short list to buy next! Thanks for all you do for the Mustang community and producing a plug and play solution for guys like me! Keep the YouTube content coming, love your channel. I do have a few questions for you regarding the AC, but I’ll send those to your email when I order my harness.

Sounds great! Thanks for your support!

Wish I could do a swap but around here the emissions rules are stupid. Not only does all the emissions stuff have to pass (no beef there) but the engine can't be different from the VIN.

On a side note, a couple years ago when I was chatting with the guys from FP, they said there'd be issues with a Gen3 system in an S197 due to wheel base differences throwing off the ABS/TC. Not sure if that's accurate, resolved, or what.

I've seen many coyote swapped Mustangs but I don't think I've yet seen a one that is a fully functioning S197 with a coyote (all electronics, safety, emissions, PATS, etc). Unfortunately I'd need some serious convincing that all these have been solved before I fork out $$$$$ on a swap project.
