beautiful!!! great to see it - those gen3 guides are SOOO beefy compared to gen2. did you also do the lifters and rollers? thanks for sharing the photo.

thats really interesting. Does the ford diff cover claim to increase rigidity of the front diff housing? I read through your thread and had to laugh that people were recommending to JB weld or TIG + JB... o_O Im going to buy a spare housing to take apart and see if I can learn anything...

Gen3 3.5 engine is more robust then a Gen2 3.5L Gen3 rear axle/suspension is superior Gen3 frame is stronger Gen3 front suspension, spindles, hubs and ball joints are superior FYI: The 23 gen 3 can be tuned if you swap a 21-22 pcm. Worth it.

Thanks for letting me drive your mid travel down the embankment. I needed that.

Does RCV make them for the 2021 3rd gen knuckle? And pardon my ignorance here can you explain how is the delete better than removing the vacuum line altogether? I am nervous about the overall strength of the aluminum front diff Housing..

the rear axle and links went together like butter. Its a pleasure not having to deal with leaf springs, u bolts, and shackles/bushings! I used 5/8” grade 8 hardware to allow the hardware to install/remove without worrying about fuel tank. (Future self :banana-mario:) I saw this idea from...

The biggest strength improvement in the gen3 strut tower is this small seemingly innocuous piece of metal at the bottom of the frame rail. This ties the entire structure together and would have saved my gen2 from cracking/breaking. if you have a gen2 this is cheap and easy for any half decent...

It’s worth inspecting the bypass valve. Also a good idea to see if you have any codes

Axle was in good shape - A broken elocker bulkhead was the only casualty. I had some fun figuring out the electronic parking brake and plan to retrofit that in place of my cable. Axle now has 3/16” 4130 gussets everywhere: I carefully stitch welded and reinforced and gussetted the front of...

Going to be a busy weekend!

HO pistons are cast, hyper-eutectic aluminum with a steel ring carrier. This is similar material and construction to non HO pistons. The difference is compression ratio and oiling ports

That is a great work area for a project like this. You could leave the truck running as-is and get a longblock together. Then swap it when you’re ready There are pros and cons to building a used motor vs building a new motor. I’ve had good and bad experiences both ways. If new, buying a bare...

As you might imagine, the crankshaft failures are catastrophic and it’s difficult to take anything conclusive away. My speculation is I belive the harmonic balancers are failing and causing stress riser fractures to grow along the counterweights. In almost every high mileage raptor I’ve seen...

In your area is one of our former employees from Full Race, he now runs https://calvo-motorsports.com/ - an accomplished engine builder/installer. I can put you in touch with him if that helps there is nothing quite like doing a project like this yourself. The key is you must have a lift and...

Headgames is a specialist, my go-to for cylinder head prep only. They do not build engines or support turbos. Likewise Full Race is a specialist for air and fuel (turbos, intercoolers, fuel systems and supporting components). At this time neither of us have the bandwidth or resources to...

I’m not sure if the commentary is because you think I’m being argumentative - that is not my intention. my point is responding to the statement a non HO gen 2 will not work in an HO application. without any technical reasoning, I don’t see why this would be the case. Again no intention to...

@letsgetthisdone yes that is 100% correct. If the end user needs to re-orient a fitting for whatever reason - it's simple and easy to adjust with the pinch clamps - double oetiker clamps would remove that ability. let me know if you have any other questions

I know the gen 2 HO pistons are lower compression - yes. But be aware gen 3 are all the same and has the high compression just like Gen 2 f150 non HO Also the gen2 HO cranks seem to break. Gen 3 cranks do not fail and are a cost effective direct fit to Gen 2 Hmmm that has not been my...

Headgames just sent me this photo of the all new Gen 2 Raptor valves from SIvalves. They are numonic 90 on the exhaust and ev8 intake valves. Wow I’m excited.

@FordTechOne why does it need to be the HO? I am not meaning to sound ignorant, I truly can't find much differentiation outside of the turbos and downpipes/exhaust configuration any chance you have a photo of the harmonic balancer/crank pulley from the failed engine?

ML3E is the base 3.5L (non HO) engine. As far as I can tell they're the same as the raptor heads. I could not find any difference in alloys, oil galleys, etc. The valves are different materials, although the cams and valvetrain are virtually identical the MLE is a 3.0L nano engine used on the...

The more common valve train failure is the Gen 2 plastic guide, it can fail at the pad where the tensioner pushes on it. Ford updated the tensioner and went to a metal guide on the Gen 3 Gen3 Metal Tensioner Arm - Driver's Side (LH): ML3Z-6K255-A Gen3 Metal Tensioner Arm - Passenger Side (RH)...

100% agree, these trucks are awesome. Well worth the effort to get right. I’ve reached out to MMR and they didn’t seem overly eager to support these engines. I hope that sentiment changes once warranty’s end and serious enthusiasts start taking their 3.5L engines into their own hands like the...

Wow you are ahead of the curve!! I like the GSC spring kit the most, Dave @ headgames talks about those springs a little in their video if you get a chance to watch

If it’s chassis or suspension I’m referring to gen 3 raptor If it’s engine - any 2021+ 3.5L is a gen 3 ecoboost and has the good internals
