'11/'12 and '13 block differences

[JEWC_Motorsports]

So if you had a newer design you wouldnt want to know about it? Hmmmm i know i do. If the late 12's have block off plates on the squirters its possible for us to have the 420hp. Not a big deal to some, but could be cool for others.

I understand.

Well I'm very interested to know what pistons I have. I guess since I have a 2/22/2012 build date I have one of the last 2012's made since they started producing 2013's on 2/27/2012. The squirter delete and updated/redesigned pistons for the 2013 could have been a cost cutting measure but I'm gonna stay positive and hope it was a performance related change. As people in the know dig deeper maybe someday we'll know for sure why Ford made the changes.

Since we are talking about the blocks. Does a 4r70w trans bolt up to the block? It would be a manual valve body.

There have been a few to run the 4R70 with the Coyote motor.

so then a motor with the new pistons and oil squirters would be stronger than both?

Stronger than both? What does that mean? The 2013 pistons have the gas relief groove cut into them and also have the new heat treatment to make them stronger. As far as the deleted squirters I guess that can be debated as to whether it makes a better motor or not. Someone smarter than both of us knows the answer and maybe one day we will all know why Ford deleted the squirters.

L&m just built a 2013 motor and they had the squirters! Confirmed from the horses mouth

Where are you guys finding the full build dates at? All I can see from mine is 2/2012 on the inside drivers door panel.

PM tmcolegr on here with your 17 digit vin number and your email address and he can tell you your exact build date. He's done it for me twice now.

Unless L&M (the horses mouth) comes on here and posts that up, I'm calling BS.

I can do that as well. I just need the last 8 of the VIN.

This sounds about right... see below:

For this review, we'll use the 5.0 Mustang GT engine, the Coyote, as the starting point. If a part isn't mentioned here, such as the block, you can reasonably assume it was carried over unchanged from the 5.0. Curiously, the Coyote's piston squirters were one of the first things to go because at high rpm they resulted in massive windage. There was just so much weight of oil whipping around in the crankcase that it slowed the crank and rods, costing horsepower. But without the piston squirters the Coyote's hypereutectic pistons were on the durability edge.

From that article it would seem that Hypereutectic piston durability was the main reason for those squirters. If Ford deleted them in 2013 engines, it would follow that the new(er) pistons are stronger, yes?

[Rob72]

^When the two engines are retuned to max out their performance they both appear to have the same amount of max horsepower. I think that the 13's pistons are hypereutectic also. The difference is that they have a phosphorus coating and more heat relieving passages.

Coyotes are sleeved. They're just thin sleeves. Only the GT500 uses the plasma bores.





This.



The bolts that come in the new block have already been torqued. You'll probably want to order a whole new set. They torque them down to spec when machining the block.

I recently built a '13 block and ran into the same issues as the OP. The 11/12 and all prior modular blocks have the head bolts thread deep into the block. The '13 block is much like the old pushrod blocks where the head bolt threads are just below the deck surface. Head bolt torque spec's are slightly different as well (18lb/ft, then a 180 degree stretch).

Here are the two head bolts:

IMO that's is a bad idea on ford's part. the long, deep bolts avoid block distortion. bolting onto the face of the block is to save money IMO.


deleting squirters? cost savings, maybe a slightly lower volume oil pump.... sounds like ford gained hp from less drag.

 

[19COBRA93]

To save money? Do you have any idea what R&D costs? How exactly are they saving money by shortening head bolts? Ford is absolutely not going to go backwards in strength or reliability to save a few bucks. Not these days. The '13 oil pump is the exact same one as the '11-12. And we all already know the extra hp came from deleting the squirters.

I'd choose a revised block any day of the week.

Also, the new head bolts are fine thread, the old ones are coarse. More clamping force with the new ones.

This made me think about when Ford revised the short block in '93...going from forged to hyper-u-crack-em pistons.

Oh, you mean 20 years ago when cars were shit, and Fords big bad Cobra made 240hp? It's a bit different now.

The shorter bolt will stretch less under variations in operating tension than the longer one - it will maintain more consistent pressure on the head gasket at high engine loads or with boost.

omg I am liking these answers lol

yay for '13 stuff!!

I was SO tempted to respond to the earlier message with "Wow! Look how much they stretch!". But I didn't. ;-)
