GT350 Motor Swap

[PatriotGT350]

Valves and springs on the driver side bank successfully relocated themselves into the oil pan. Other parts have joined them. Warranty expired less than two months ago and now I’m faced with the dilemma of replacing my motor out of pocket.

A new voodoo is just too expensive, so I’m thinking about a 5.0 swap. Any advice or suggestions are appreciated. I love this car and I’m absolutely devastated by this. Viewer discretion advised on the photos.

I'd do a teardown and see how bad the damage is. You may be able to salvage the block, sleeve it, and convert to CPC. That would have been the route I would have gone if I didn't get a deal on a built motor. That would definitely be cheaper than a new Voodoo. My guess is it would be roughly what a Coyote swap once everything is factored in with the benefit of having a sleeved block if you decided to build it out in the future.

Thank you! I'm waiting to see just how bad the damage is and whether or not the block is intact. Still too early to tell.

Hoping for the best for you man. If the block is still usable, I'd sleeve it, convert to CPC and re-pin the harness, and replace everything that has a cavity which touched the oiling system (hoses, oil cooler, cylinder head covers, etc.). I tried my hardest to clean my cylinder head covers but there was just always aluminum dust still in there. Sonic cleaning the parts is another option if the damage didn't cause a catastrophic level of metal dust to be pushed through everything.

If block is salvageable, I vote getting that cleaned up and rebuilt as a Voodoo or CPC 5.2. Can't tell what kind of damage the head has or if having the valve seats/guides repaired is cost effective on these.

I rebuilt my 5.0 in my garage in 2020. Had Duffee Motorsports clean up the block and balance the crank for the piston and rods I brought him. It's been flawless so far and lasted many more track days than the stock engine did. These are easy engines to work on, just rough on the wallet.

Did you contact Ford Customer Service directly? I'd be looking at some help with it failing less then 2 months out of warranty.

I you should definitely check with Ford and your Dealer. Two months out of warranty is pretty close , but do it soon and let us know if you have any luck. Do both , check with your Dealer and Ford Customer Service, not just one.

Like Bill said, check with Ford directly. Let them know you are a fan of their product and several other enthusiasts encouraged you to contact them because of their past “extensions” of coverage. You have nothing to loose.

Good tip on calling Ford. I've had such bad experiences with customer service these days that I assumed I'd be told "too bad", but I should at least make the call and see. I did speak to my dealer yesterday but they just started talking about cost to replace the motor. I'll try Ford today.

Sorry to hear, that's a bummer. +1 on the suggestion to covert to CPC and repin the harness. Lots of people that track their GT350's often seem to go that route. I will be doing so once my extended warranty expires.

Another option, although not the best one, is you could get a take-out engine from a wrecked 350 from www.thepartsfarm.com

I get the feeling that the customer service will tell you that 1 day out of warranty is the same as 20 years out of warranty...

I'll join the others and say that if your block isn't catastrophically damaged, I'd sleeve it and rebuild it with a CPC. Basically gives you a GT4 motor !

Thanks for all the suggestions! I reached out to Christian at Ford of Upland and he's working on a solution for me. Great and knowledegeable guy that is definitely here to help the Mustang community. Restoring my faith in Ford dealers!
