Well, the current plan is to simply buy a new 351W from Ford, and also the matching computer... model year 1994. I'll handle the performance stuff after I blow that engine--which will be awhile. Going to have to find intake and wiring harness, which will be F U N, if you catch my drift... I don't want to spend what Ford wants for those items...

Banking on about $2200 for the engine (minus exchange for my 302 if possible), $220 for the computer, and maybe $400 for intake and wiring harness... Another $1000 for labor if things don't go as easily as planned. So looking at about $3820 for the entire job--but will have a new engine that stands a chance at being "fun" to drive...

(And I'd still owe less on this than on the V-6 F-150 I traded for it!)

Fordman: your correct it does have a different firing order. But mine won't be going with EFI. I plan on a 4-barrel, seems cheaper than a $600 swap for a MA system...

A buddy of mine in hs had a well worn out 88 3/4 with a 200k 351 that was a real pos. He bought a 351 from Parts America for 600 dollars and installed it himself, he used the original intake and the orginal wireing and everything else.

I deffinantly don't want a stock 351, with only 50ft/llbs and a whole 5-hp more, It would be cheaper to just build up my 140k 302.

I'm not talking about swapping the intake. I was pointing out if you're going from a computer setup for a 302 to a 351W, you'll have to either get a new computer or install a 302 camshaft and distributor. Intake stays the same.

 

The trick for me is going to be finding used parts to save $$... I've asked around--hope to get some e-mails back on this. Sticking with EFI "just because" but think it'll help to stay emissions legal as possible...

Reliability is another concern--since I'm pulling live horses all over the country...
Fell more comfy going with new parts from Ford except for the minor things...

Ya, we already know that.

Mike, I understand that, and the 351 is a better "puller" than a stock 302 could be. do you know if the "94" computer is Mass air or speed density? You may want to go as new as possible (96). I think my dad's 351 in his 95 was a MA, but not completely sure. Hopefully you'll have a noticable difference with your 351 over your 302. I wonder about emissions too, would EFi vs a carb be any different for passing emissions?

What about finding a 93-95 Lightning engine from a salvage yard, and freshening it up if needed. You might be able to also get the wiring haness and computer too.
The 351 Lightning motor is awsome, from the factory uses a speed density system, and I see there is a guy who is selling the mass air kit for it in the classified section.

------------------
1999 F150 4x4 4.6V8 regcab/shortbed
Oxford White with Wedgewood Blue two tone, with Blue Captains chairs
Bassani Cat Back, Superchip,Modified intake with modified K&N filter.
Centerline Saber rims 17x8" with Firestone GTA 275/60hr-17 tires.

 

A lightning in my case wouldn't be too bad. Finding one will be hard. They had GT-40 heads, and a few other things, that produced 240hp, not sure of the torque rating. I assume 330-350. Even if I could get some parts off it, (heads!), I could build a really nice 351, I could even build a 302 and put the lightning heads on it.

Don: Can you tell a difference between your lightning and your 4.6L? What im saying is a seat-of-the-pants difference?

'94 351W is mass air. The dealers I've spoken to have all recommended the '94--I think it's a fit issue...

-Mike

 

One of the two shops I've check with can stroke my 302 out to 347ci... This doesn't sound like a bad deal and would DEFINITELY be less expensive than trying to find/install a 351W, computer, etc.

Thoughts? How would this affect durability??? I'm a bit hesitant to get 347ci out of a block made to be a 302...

-Mike

 

Stroking a 302 will give you some good torque, but you need to keep in mind it won't be a high revving engine. Mate a good cam to develop your peak torque down low, maybe 2800 revs or less. This will probably be just fine since you're wanting to tow a horse rig.

 

I, in the early posts, described boring out of the 302. Its overboring by .0360, I think. The 4-wheel and off road magazine did a overbore on a 302, out to I believe .0400, to 355cid. Even if a guy did it, you can't run a SD system with it. Everyone and (including me) say boring a 302 past .0300 wouldn't be a good idea. The walls would be paper thin. More like a 500 mile motor. I believe they push around 350hp, I wouldn't advise it, myself.

I would think youd be better off building a 351, or even a 302.

A guy emailed me, about a takeout 302 out of a 86 mustang, completely stock, he's puttin in a crate 5.0L. He wants 350 dollars for it, and its a CFI injected. CRAP! I allready know its reliability. I wouldn't mind having the roller cam 5.0L and build it to 300hp.

 

You can safely get away with 0.060 over before you start hitting the water jackets. I wouldn't make that a concern. There's no reason overboring won't function with your current emissions.

 

Mike: Another member here discussed the rebuild of his 1992 302. Like I mentiuoned before, the computer will have a Shi* fit if you overbore.

He has over 200k on his original 302. Not bad! www.f150online.com/f150board/Forum37/HTML/000055.html

 

Overboring by .030-.040 will not upset either a S/D or MAF EEC-IV processor in the slightest, a .030 overbore is only 306 CID. Stroking by 7/16ths or so to 347 will probably affect the S/D version though. S/D processors don't tolerate significant changes in volumetric efficiency from cams, heads or especially supercharging. Stroking will obviously increase the swept volume and may change the efficiency enough to fall off the "map." If you stick with the later MAF version, no problem.

 

Strange: A guy asked me awile back if a TB spacer would work on a SD system, I told him no. Is this correct, or will it allow a minor change?
