hey i was wondering if anyone here has ever done a 347 Stroker engine swap. I was looking into a V8 swap. If i do do it i want to go bigger than a 302, but not so big that i bust parts like crazy. Looking for at least 400 Hp. i know chevy 350 small block are cheap, but i'd rather stick a Ford engine in a Ford truck. Also i am not fond of the fitment issues. thnkx

 

I think it's a good idea but likely to get expensive, whether it's a 347 crate motor or a 302 plus a 347 stroker kit.

 

347 stroker kit is a great kit to do for a 302 if it needs a rebuild. pretty much gives you everything in it. take it to the machine shop and away you go.. now for a newer truck like yours you will need to do different trans and i beleave people have used an manual transfer case from an expedition, also you will have to decide EFI or carb. both will present a list of issues you will have to over come just to make it work...

 

for the motor itself your looking at $2100 just in the kit, plus machining costs which should be around $1000 with assemble easy... then there is the whole trans/transfercase/wiring issues...

 

How about a 351?

 

i dont know how you get get 351 out of a 302. Isn't a 347 pushing the walls to the limit??

 

347 is the limit. Maybe he is talking about a 351 Ford block, but I believe that would take a lot to fit into a ranger.

 

Yea i'm talking a 351 block instead of a 302. He said he likes the 350 chevy, so that would be the ford equivalent. I've seen a couple of trucks with 351 but the were Gen II's

 

I'm sure that a 351W swap is possible but the basic long block is a couple of inches taller and wider than a 302. That doesn't sound like much but the smaller 302/331/347 is already a tight squeeze in a 98+, especially on the passenger side. A 97-back Ranger would be a better candidate for a 351W swap.

 

Vortech 6.0 is cheap and has about 350 hp and 380 ft/lbs stock.

And its roughly the same size as a 5.0L. I know you said you would like to stay ford but its another option.

 

Yea a 351w is an option but i don't like the fitment problems. i was not sure if a 6.0 Vortec would fit. But if it is roughly the same size i might be worth considering. I also was worried about the weight issues in bigger blocks. About how much does the Vortec 6.0 weight? I looked into cast aluminum block but they are a little out of my price range. I do have a BL which might help on some fitment issues.

 

from what i have been told from some of my friends who build/race mustangs a 347 is more of a performance motor, it can be driven on the street, but a 306 or 331stroker build up would be more practical and a bit more reliable.

 

Also, cant forget that if you stroke a 5.0 Explorer or Mountaineer motor you will have to use a 50 oz. crank balancer since most of the 347 kits are for mustangs which require a 28 oz. crank balance.

 

the vortech block from what i gather is the same size as LS1 and chevy 350. you would most likely need to swap a car oil pan on as the truck pan is really big.

 

306 or 331 would be best...a 347 is more all out race in my book since it puts the 302 block at its limits...but anything is possible..a guy in town has a 460 in his 96 single cab drag truck...depends where you wantto put your money

 

How is a 347 more of a "race" set-up? Its the same bore as a 331 with more stroke. IMO you'd want more stroke for more torque - Its going to help with towing, hauling, etc etc. Also, when you stroke a motor it increases piston speed/travel, so in theory, you could receive the same or better MPG as you did with the stock stroke.

347 is where its at in my book.

 

in the process of a 347 stroker. needed a rebuild on the 302 so said screw it and started it. cant wait for it to be in!

 

you are also adding compression when you stroke and engine. There's a good article going in FOUR WHEELER magazine where they are punching 4.6L out of a 4.0L AMC/Jeep engine. Lot of good bore/stroke info in there. I think it's Nov 07 and Dec 07??

 

thnkx but like i said i would want a more power than what 4.6 could offer. I figure i do spend all that time in doing the swap i might as well make it worth it

 

a 351w has only like 5 more hp stock than a 302, and a 347 would kill a 357 in torque for about the same price

 

sorry man...i was just responding to the "race engine" comments. small block chevy offers the biggest aftermarket out there....just wanting to bring that to the table.

 

400hp is attainable with a 302/306 but pretty easy with a 347.

I have a buddy of mine with a 347 in his 79 pace car, and with ported victor jrs, a comp xe282, victor jr intake and 650 mighty demon it made right at 392rwhp with a 3550.

Pretty decent setup . . . I guess you could run a systemax or something if you stayed fuel injected.

 

Go to diesel, easily obtainable power and better mpg

 

I wouldnt do it, for several reasons.

1) Its illegal. Good job on research.
2) A 347 is a 302 block, you can get a 302 that runs fine for cheap enough, why tear it down and rebuild it when its not needed. Again, research options.
3) A 347 is the technical limit for the block, but its not going to cause any real weakness is the block, because they are designed to be bored for stock rebuilds and such (yes, there are reasons to bore a motor when rebuilding to stock)
4) Its not $2500 or whatever for the kit, they arent that expensive. Research is your friend.
5) Its illegal
6) No inspection can be done, some states thats a problem. No inspection in said states = illegal (research, common thread?)
7) Have you done it yet?

Reasons I would do it
1) Its illegal (its fun to mess with the cops in a small town)
2) 98+ trucks it will bolt in, so why not do it?
3) Cool factor (all the cool kids have them)
4) why the hell not?
5) research - people are researching this all the time, why not help them out?
6) 1300+ hp is very obtainable with this motor, but then you would be pushing the limits of the block (compression + boost = boom, also, weeeee!!!!!!!!)

Research is your friend.

Need exhaust manifolds?
