GT350 gets a new FP350s crate engine

[Gogoggansgo]

Okay kinda random but I just realized that the Mustang GT4 uses 5.2L V8.

Do you or anybody know what the difference is between the FP350 and the engine in the Mustang GT4?

Im guessing they based off the same engine meaning that its basically the Voodoo engine but is cross plane, but with some differences?

off hand i don’t but frpp used either a cross plane crank or FPC 5.2 depending on what race car it was. The gt500RC was FPC, They both will be within a few horse of each other so it really doesn’t matter lol

Okay but basically they are all the same engines just small different changes?

it’s largely the same as the Voodoo/FP350S/5.2 XS, but there are some differences due to both regulations and improvements.

For example, it uses the CPC to help get more torque in its de-tuned configuration. There are some changes to the valve train that aren’t widely reported, tho there is a secondary chain guide that was developed and released as a Ford performance part. It also uses a standard 5.0 intake.

but it’s not a Ford performance engine. They’re built by Roush Yates and from what I’ve heard they’re pretty tight-lipped about changes and tweaks.

Does the use of a CPC change the torque curve? Would it have more power down low and not need to rev out to hit the power, as is the case with the FPC?

Correct. CPC offers more torque lower in the RPM band and the FPC smooths out the high rpm stuff and gives you a bit more rpm.

@VoodooStang Would love to get an update with some video when you have the car back up and running.

Getting ready to drop a clone of this motor in a Fox .

Debating the GT 350 intake as used in this motor. versus CJ used in the 5.2 Alluminator.

planned use is street /occasional strip .

pros / cons .

Already have the GT 350 intake .

yeah you’re not going to magically get another 20whp because it’s a cross or flat plane crank.Frpp did it for reliability at the track. I believe the gt350rc is the one with the FPC but don’t quote me

You are correct, The 350C was a Flat Plane crank and won the championship in class.
