351w or 460

[TAPOUTJOHNNY]

Hey guys I have a 95 Ford F150 with a 302. It's a short box reagular cab 2wd 5 speed. It's also lowerd 2". I have a chance to get a 94 351w or a 84 460. I goin to rebulid whatever one I get b4 I put it in. I was just wounderin what motor would be better n what I would need to do to fit the motor in my truck. Also what would be cheaper to rebulid. If anyone can help me thanks.

ok, basically either can fit, a 351W is a direct swap, is your truck MAF?

if so then go 351W. easy decision. cause then you wont have to swap anything, and you can get a bigger cam.

a 460 would require a radiator swap, trans swap, comp swap, wiring harness swap, engine mount swap.

for the 351W you can do a ton of stuff to it.

and relatively cheap

Long Tube headers
Flat Top Pistons
GT40 heads (hard to find) I personally looked for 3 months straight and a year off and on...
Cam
1.7 RR's..

351 would be easier, but the 4sexy would be so much cooler....

'Which would be better?' Is in the eye of the beholder. I like the 460, but damn it would be a bunch more work getting it in there...and it's carbed. I think either are easy to build. You're comparing apples to oranges though, the W is a high revver and you'll get similar characteristics to the 302, while the 460 is a torque monster. That being said, I prefer the 460, but in yuor case I'd go 351...you'll be able to bolt that in. If you go 460, you'll need a new tranny and if you go with an E4OD you'll need a stand alone computer, or you could go C6 and lose the OD...or go with a manual. You'll be money ahead going 351W.

another thing is, make sure the 94 351W is a true 94, then that would mean its a roller cam ready engine, that would make like for choosing a cam much easier...

 

[flareside_thunder]

I wanna see pics of the truck......and I'd go Windsor.....much easier of a swap and you can make mad power without stopping at every gas station.

460's are really cool, but for every day driving, lack of fuel economy and extra cost and effort to put it in, I would go with the easy to rev, cheaper engine parts and quick swap 351w. Nice truck too.

 

[TAPOUTJOHNNY]

So a 351w will bolt up. Don't have to change motor mounts, computer, or anything? If so I was wounderin if my heads on my 302 would bolt on the 351 cuz they r shaved or would the GT40 heads be better.

 

[5.0Flareside]

GT40 are better. smaller chambers and bigger ports. only thing is you'll need to drill out the bolt holes to fit 1/2" bolts..

but im not sure bout that cause i just bought some GT40 heads and my 351W bolts fit perfect...

and the computer just depends if its MAF or Speed Density. if its speed density then yes change the computer but nothing else...

I came across this bridge i was gonna go with a 351 but since i plan on going with bigger tires i opted to pick up a 460 for the tourque and mildly built im hoping will put out as much if not more than the 351 would have but for your application id go with the 351

 

[flareside_thunder]

The computers will make a difference as the 302 and 351W each use different fuel curves......You'll run leaner with the 351W engine and 302 EECunless you get tuning software like Moates QuarterHorse or TwEECer. Sorry I assumed the 351 you were looking to buy had stock heads which will be E7TE's (the same as factory F150 302's) If not, and it does have GT40's, the the GT40 heads will definitely be better but porting will make them even more efficient. However, the GT40 has LARGER combustion chambers than the E7TE's...so the compression ratio will dropto around 8.5:1. It wouldn't be a bad Idea to have them shaved either.

 

[TAPOUTJOHNNY]

Well thanks I'm goin with the 351w. About how much will it cost to rebulid it. I seen that some of u guys have had it done. So I'll probly buy what u guys have for a cam n all that if u could help me out

 

[flareside_thunder]

PAW has good rebuild prices......Get a good RV style cam ifyou want good torque and a mild build.

 

[TAPOUTJOHNNY]

I was sayin that the heads on my 302 r shaved n portted. I think he said he spent like 1,200$ on them to get done so I thought that they would be better then GT40 heads. I just looked it up n a 351w with out GT40 heads only have 5 more hp then a stock 302. A 95 302 has 205hp the 351w has 210hp. But the lightning has 240hp cuz of the heads I'm guessing. Now after seeing that I'm not sure if I should just rebulid my 302 or a 351? I just want it do be a fast truck n cheap. But later down the road keep adding to it. Not sure what to do?

 

[crzybil87]

well, is the bronco your daily driver if so I'd go with the 351. If its not you DD then go with the 302

 

[flareside_thunder]

The L made 240 HP because it had the GT40 heads, the L GT40 intake set and a different camshaft......I have a 302 in my truck....personally I'd go with a 351W.

It's possible they are better but it's also possible the guy wasted $1200, the only way to know is with some flowbench numbers and your average joe doesn't have one of those. But even if they have been improved these heads are much too small for a 5.8 in the big scheme of things, you should be looking at some aftermarket heads from Dart or RHS which can be had for as little as $1000.

What those specs don't show you is the difference in the TQ curve between the two motors, and there is a big difference let me tell ya. I have had both in my truck and the 5.8 is an easy 3seconds faster 0-60. And the Lightning only produced 240hp because of the relativelty small cam it got due to being an SD vehicle, the 5.8 CobraR Mustang was rated at 300hp with the exact same motor but with a better cam and mass air.

I'd go with the 5.8 here too, it will produce a much better handling vehicle than the 460 and with a few simple and cheap bolt-ons it will run circles around the 5.0.

Your statement only really applies to the SD system, with mass air either motor will run quite well on either computer because there isn't much difference in the airflow through the two motors and because the mass air system can adapt to these differences. Once the motor is built up to flow significantly more than stock then yes.. a tuner will produce the best results and then it doesn't matter what EEC you start with.

However, the GT40 has LARGER combustion chambers than the E7TE's...so the compression ratio will drop to around 8.5:1. It wouldn't be a bad Idea to have them shaved either.

Actually the GT40's and E7's typically have roughly the same size combustion chambers.. 62-64cc, it's the GT40P's that have the smaller 60-62cc chambers.
