Did they remind the ecm or did they use a different ecm

Used the GT350 PCM

The FP350s crate race engine comes with a wiring harness. No re-pinning

Is this the same engine from the GT4 car?

I thought it was the same engine. Would you mind making a post with the exhaust once everything is all set in place? I wonder how different it will sound from the normal Voodoo

Don't these require a rebuild every 40 track hours?

Ford Performance‘s recommendations are very conservative. Feedback from others running the cross plane crank 5.2 liter Coyote engines on track estimate their rebuilds are more like 80 track hours.

Any Ford engine recommends that when in race conditions--whether this, a stock voodoo, or a built race engine.

Based on what I've seen from my own build, 60-80 hours is doable with a properly built race engine.

Ford Performance‘s recommendations are very conservative. Feedback from others running the cross plane crank 5.2 liter Coyote engines on track estimate their rebuilds are more like 80-100 track hours.

That's because they're trying to fix things before catastrophic failure. Not sure I'd push any engine that hard for that long (unless detuned a good bit).

Not to deviate from the topic of this thread, but whereupon does a stock 5.2 GT350 engine typically require a rebuild based upon track hours?

Really depends on how hard you're pushing. A stock engine with a stock tune getting pushed hard is probably good for 80 hours of use. Tune it for more HP? Reduce that a bit.

The best thing you can do is stay on top of maintenance, oil analysis, and testing (compression tests/leak down, etc.) and keep an eye out. That'll help with just about everything except valve springs. I'd be worried about the stock springs in a stock engine at 60+ hours of HEAVY track use (for reference, I'd argue this is within 2-3 seconds of the car's ultimate capability).

The FP350s engine has the road race oil pan, GT350 intake & flywheel clutch and pressure plate
