My guess is frpp saw the new duel intake and said hey we can make that for the previous gen cars. It also uses the gt500 TB my guess is it probably won’t fit or won’t have any major gains on the gen 4 engine point being the new cobra jet is designed to give the older cars the current duel...

This gen 4 engine is based on the 2021 f150 engine aka the gen 3.5 engine if you will, ford switched to external oil pump gears. Also oil pump gears aren’t really an issue unless it’s a gen 1 or maybe a gt350 DONT lose sleep over it

I’d throw in a better dry filer and leave the stock air boxes. With two throttle bodies unless these new boxes have some sort of restriction you’re wasting your time and money

I wouldn’t either because it’s not final remember when the gen 3s came out tbey wanted to keep that cover real quiet lol

I’m glad they went with a new name, after a while it gets old rehashing crap. Because let’s be honest here if they called it a cobra or boss 302 half of y’all would be disappointed it didn’t have this or that. But when it’s a new name plate they have some breathing room to experiment

Steel is a lot easier to stamp out i love aluminum but it’s such a pain to get right lots of splits

I doubt they increased the stroke significantly because piston speed is a real problem on the mod engines once you hit that magical 5.4 number. They probably made an updated block for the race car to increase bore spacing. Unless they’re using some titanium connecting rod I’d be surprised if...

With one key difference it’s not a small production variant like the boss or gt350 excluding the fact the gt350/500 was hand built. What really slowed them down was the CNC heads it took 2-3 hours per head. Which for a mass production vehicle isn’t cost effective. Which is why the dark horse is...

They’re probably going to retain the current boss 302 sinster rods which go back to the gen 2s the 5.2 rods are a good bit beefer

Gen 3 vs gen 4 using automation

Redline didn’t change

That front end is a million bucks it looks bad Ass

i can’t stand him he’s a total chode

You also have to watch for whether or not the Ecu has built in traps for piggy backs. BMW has been doing it on some models it throws an implausibility code and gets recorded so the dealer can see it It’ll see the map is reading extremely low and go yup we got a piggy back then check the other...

Valid point which is why it’s going to be either a remix engine or a real gen 4 update they’re going to have to increase revs, or mess with the intake substantially. We shall see today

With all that blurring it looks like a Ferrari Roma Lmfao

Piggy backs have been a thing for the euro guys for years and it’s going to be the hot ticket going forward it’s both good and bad

This is 100 percent correct, it’s a great engine buts not going to be an engine down the road in 10 years people go wow i gotta swap that. Which is why the gen 2s are still the hot ticket for the big power builds

Considering that new cobra jet intake i bet we see a production variant

They had a lot of piston wall clearance issues resulting in a good number of failed engines. Aka the tolerances were too tight and because it’s a semi open deck block, it would cause wall damage. You can just do a google search on the early engines. They also had some oddball VCT issues and some...
