5.0/5.8 or 4.6 DOHC?
Well I have come to the decision to replace my original 300 6 cyl. and 4 speed in my 66 Slick with an EFI V8 and Auto/OD unit. Just wanted to get an opinion and with your opinion, some advice on how you did it. I am considering either a 5.0/5.8 with an AOD or going all out with a 4.6 DOHC Mark VIII driveline. So chime in and tell me about your experiences.

the Lincoln drive train is by far the most complicated but reaps the coolest factor and stock bang for your buck if you go 5.8 or 5.0 I would get maf system with a aode in my 61 ford falcon I had a map sensor 86 mustang ho with aod never really performed well then the trans went out for like the third time in two years and I bought a 95 mustang ho maf sensored motor and aode two years and noooo problems but maintenance if you can find the Lincoln package cheap enough maybe the whole car for everything it's what I would do

Thanks Jack. That has been kind of what I was thinking. The Lincolns are fairly common and cheap around here. I was thinking of going with a 95 or newer Lincoln for the swap if I do it. The reason for considering the more conventional push-rod engine is I have found an F150 in good shape to be a donor and the price is right. Still not decided yet. Anyone on here ever done a DOHC transplant into a slick?

I put a '91 Mustang mass air motor (but with the T5 trans) in my '64 Falcon. Since you have already done similar, you will already be aware of most of, if not all of the pitfalls. While there's plenty of room in the engine bay of your F100, I don't find a lot of spare room inside the cab. Boss 9 is having the same (adequate space) problems with his current project. If you're gonna take any of these engines, you might as well keep the power steering and air conditioning pumps/compressors that are built in to the serpentine belt system. But that may cause some packaging problems inside, depending on what kind of a/c you choose. With the automatic and an evaporator hung under the dash you might be OK. Where are you going to mount the computer? I would imagine the DOHC engine probably has a lot more plumbing to find a home for than the 5.0/5.8. Whatever you do, it'll sure be a nice truck when you finish. Good luck!

Osiyo59, I put a '92 5.0 w/ AOD in my '66 after the original 352 caught on fire back in 1997 and it is still going strong. I mounted the computer on top of the glove box. Power steering is a no brainer with 92 pump plumbed to a 69 box. People love to see the fuelie under the stock sheet metal.

Well, after a bit of searching for a donor vehicle, I have settled on a 1991 f150 with a 5.8. I still have to find a transmission but the rest of the truck will be good for everything else. It's a 4x4 with a bad trans and since I have a 2wd, it doesn't matter. The owner is asking for $750 obo. I figure I should be able to get it for about $650. I'm gonna use the engine with the EFI along with the harness, wheels, and power windows and locks. I can then turn the truck over to PnP for a few hundred back.

That and if you want to pick up an entire donor car you can find them relatively cheap. I have seen them them as low as $500. When the air ride suspension goes out in them it usually costs more than the car is worth to repair.

And for the most part, it's the same engine. Horsepower rating is a little less but the same engine. The following paragraphs borrowed from Wikipedia:
Powering the Mark VIII was an all-new, all-aluminum 4.6 L DOHC 32-valve V8. The engine was the first of its kind in Ford's Modular engine family. The 4.6 L V8 produced 280 hp (210 kW) @ 5500 rpm and 285 lb·ft (386 N·m) of torque @ 4500 rpm and required premium grade 91-octane fuel for optimum performance. Handling the V8's power was the 4R70W 4-speed automatic transmission with overdrive. The Mark VIII's rear axle ratio was 3.07:1.
For 1996, Ford finally did away with the aging 5.0 liter V8 in the Mustang, replacing it with a new aluminum 4.6 liter, DOHC, "modular" unit that was smoother and had slightly better fuel economy. This engine produced 305 hp (227 kW) and 300 lbf·ft (410 N·m) of torque, making the new Cobra capable of 0-60 in 5.5 and a 13.9 second quarter miles. Early models were backed by the Borg Warner T-45 5-speed manual transmission. Late in 1998, Tremec bought production rights for the T-45, although it remained unchanged in terms of strength.
