For what you want to do, swapping in an 5.0 from a Cobra Mustang would probably save you lots of pain & money. It'll be more like 230 HP & 280ft-lbs but its close and the donor car would provide all you need to get that going, like the ECM, MAF & wiring looms. Doesn't sound like you'd care about losing cruise control but there are ways to keep it. As for the transmission, I don't know if there are any issues there but most likely, as it was probably all electronic. Don't see why that couldn't all swap over though. Another alternative would be to get an engine from a Mk. VII. All of that would swap in.

Cobra upper or GT40 stuff will not bolt up to stock lower. However, an HO upper from a Mark VII or 80's Mustang is a direct swap.

Go straight for an explorer 5.0 and swap out the truck cam for a stock HO cam or some seriously mild aftermarket cam and you'll be at your 250/320 goal easily...you may even pass it...cobra and explorer cams are all about torque and HO motors from some 90's 5.0 tbirds had the cobra cam...they're great torque cams, but your goal is more easily reached without them.

Explorer motor is the best batch of factory 5.0 parts you can get for reasonable money. The only two that might be better are the 93-95 Cobra motor or the Boss 302 from the 70s and those you're just not finding.

And yeah, the cam and valve springs on the Explorer suck. Easy to fix, and you're golden. None of this stuff will work with the stock ECM though. It will need changing to at least Mark VII ECM, but more realistically you're into doing a mass air conversion and ideally a tune. It can work with the Mark VII brain and a tune, if you can find someone to do it.

[sick88tbird]

Will also work well with just a MAF conversion... No $1000 tune required.

[gadget73]

Indeed. Mine has had no tuning done and it runs just fine, but might be better with fine-tuning. Wouldn't run worth a shit with the Mark VII brain, but that likely could have been fixed with a tune too. The mass air stuff is somewhat easier to source and more people understand it when you get to the point of needing/wanting a tune.
