Okay guys I need expert advice before I start my build from the ground up. When I get back from Afghanistan I'm going to rip my Fox down to its bones and do a full build. So I need to know what engine will perform better a older EFI fully aftermarket built engine (347, 351, etc.) or a new Coyote 5.0 with as many parts currently available for it? Keep in mind I'll need a new tranny for both. the new Coyote 5.0 crate is cheaper and puts out more HP than a 347 or 351 crate. But im not sure if old school blocks perform better. Im also wanting decent MPG also. My car is gonna be a Street/Strip car. Give me all your possible suggestions and opinions please.

If I had the money and knowledge to do it, I would go with the coyote. More dependibility, and factory over 400hp. And it would be different, everybody and the moma got a stroked fox, not many have a coyote fox.

ME, I keep it push rod cause thats what I know.. I know how to work on them, the new MOD motors are foreign to me. I do have a Mach 4v but For me to have a track car I would rather be simple. I am sure once I torn my 4v down a few times I would know the ins and outs but haven't done it yet. But If it were me, and I was doing a full rebuild, I'd go for a 408 stroker, and if you wanna keep efi do so, if not then carb it. Since you are wanting to do a street strip car I would keep efi with a 90mm elbow and TB on a efi vic jr intake.. I would have a custom cam ground for the motor, forged internals with TFS 225's.. 1 7/8 inch to 3.5 inch collector headers for a full 3.5 inch exhaust, and some heavy duty injectors... maybe 60 pounders... Back it up with a built C4 and have a blast.. and of course have the rear end built and sfc's and all that jazz..

do a coyote fox, they are rare and would be nice to see

What does your budget look like? can you afford all the parts for a coyote swap?

[91cobra5.0]

New coyote 5.0 with a supercharger and a manual trans behind it. Keep the engine stock besides the blower and by the time anything breaks you could have learned enough about that motor to rebuild it. A brand spankin new engine isn't gona break anytime soon

[Dap1991]

when you looked at the coyote crate, did you factor in the conversion kits and all that ? also are you able to run the stock computer with the new engine or would you have to get a new computer too? what about an aftermarket block 302 based engine with a turbo? or hell, your stock engine with a turbo?

Word!

If you can afford it, then go for the coyote. If not then do a stroked 351. It's been done to death so they'll be no surprises and for a street car it's hard to beat cubic inches.

[kmedeiros88]

Stroked 351 gets my vote. Dropping in a coyote is going to cost more than you think. What are your HP goals?

[91cobra5.0]

he also asked for good mpg and a 351 or worked up 302 arent gona get near the mpg the new coyote does

[91cobra5.0]

BAM engine swap made easy

[Dap1991]

wow thats expensive and thats not even the engine or headers or anything

[91cobra5.0]

Yea those motors are like 8k

[Dap1991]

ya how can the coyote be cheaper and put out more, for the 8k on the engine alone you should be able to make a nice 351 based engine with much more power right? plus the cost of the the new harness would be another 1k saved

[STREETFIGHTER50]

Stroked 351w would be best for the budget/power choice IMO. I'd like to do one of them Coyote/Fox swaps some day, but I'll be patient & wait. Later on down the road with all the aftermarket competeing with each other those Coyote/Fox swap parts are gonna get even cheaper & more refined.

[428CJ]

I'd go with with a stroker 351 because a coyote swap is so expensive, and you could make a mean windsor with the price of swapping in a coyote 5.0.

Prices from LRS:

1)Cotoye 5.0- $6,100
2)Computer pack- $1,440
3)ceramic headers for swap- $780
4)swap oil pan- $345
5)O/R x-pipe- $270

Just with some of the main parts for the swap, your looking at 9K, which would make a sick windsor stroker.

My Comment still stands! and With a tuned EFI 408 you can still see decent gas mileage!! Hell even with a Carb... Stroked 351 would save you bones and ask your self this.. with all the extra money it would cost to do a coyote swap, will you make up for it in gas mileage and how long will it take to make up for it.... If you gear it right and have a good tune a stroked 351 would be perfect..

Im in Afghanistan and I finally could get on! I've decided on a 363 BOSS Block from Ford Racing with a 500 HP rating carbed, but I'm sticking EFI. I cant decide if I should Procharge with Water/Meth injection or N/A with Nitrous. My HP goal is about 600 to 700. Buying a brand new Ford Explorer loaded when I get back too as a family vehicle and a present for tha wife. I can tow my Stang with it if need be also. Get rid of her P.O.S. foreign mitsubishi galant. FORD FTW!
