Nope. The 351 Equipped lightning had 240 or so. The other 351's had 210 or so. The 302 has 185ish haha.

 

I think the highest hp out of a 302 in recent history was the 1993 Cobra with 240. The 5.0 H.0. in the Mustang GTs was 225 in its best years.

Go windsor; no replacement for cubes.

 

Nooooo. A 351 Lightning doesn't even put out 250 stock (240 HP, 340 ft. lbs). An EFI Truck/Van 302 was more like 195-200 HP stock and 270 ft. lbs for the torque. You need torque when talking about moving that big van anyways. I'm still for the 70's F series 460 beater idea. Maybe I'll make one eventually.

Edit: Sorry I didn't see everyone else's response about HP ratings!

 

$5000 to make a van fast?

$500 - junkyard, but running 351W EFI out of a 92-95 van or pickup.
$400 - Garrett T04 Turbocharger.
$100 - used powerstroke intercooler.
$20 - 3"x18"x0.25" steel flats (metalmart, metalsupermarkets, etc)
$30 - 1.5" ID black pipe (lowes, home depot).
$20 - T04 Turbo Flanges (ebay)
$500 - misc stuff, clamps, hoses, fittings, etc

$100 - 89-93 Mustang mass air wiring harness
$100 - 89-93 Mustang mass air EFI computer (A9L/A9P)
$100 - Craig Moates EEC J3 adapter, eeprom programmer, and cables
$ 0 - Paul Booth's "EEC Editor"

My van will be faster than your van.

If the 351W is a 92-96, healthy without any noticable blow-by (other than stock) this combination will give you about 400-450HP and about that in torque. Torque will be reasonably flat from 2500-3700 with the factory engine/intake/heads and if you put the labor in to port them at least a little bit.

I've made the following assumptions:
1. You'll chop up the black pipe with angled cuts and weld together a pair of exhaust manifolds, using bits of your factory exhaust system to make the crossover.
2. You understand EFI enough to tune in properly, and willing to put the time and effort into learning the EECEDITOR software and adjust your fuel appropriately so you can run about 12-13psi of boost.
3. You will run 93/94 octane at all times.
4. You will port your own heads.

If these numbers are unsastisfactory, port the heads, use a high-lift cam (with minimal overlap), a pair of T03 turbos, and install a 393 stroker kit which will cost you about 8$800-900 on top of my numbers above. The entire cost of a 393 stroker, twin turbo engine which should produce approximately 700-750HP will still be less costly than $5000. But you have to do most to all of the labor yourself. Making the manifolds, clearancing the block to fit the stroker kit, change and degree the cam, adjust the pushrod lengths, run the oil pumbing for the pair of turbos, modify your oil pan for turbo oil returns, port the heads, etc.

A good friend of mine finished a 393 cid stroker for his project, installed two turbos, and I helped him tune it this past April. On the dyno he broke 700HP at the wheels. Unfortunately we had to push the car off the dyno since the transmission didn't like that on the second run. See, you run the car on the dyno three times, tuning a little in between each run. The only machining he paid for was for someone to line bore for the camshaft, and overbore the cylinders, and cut the valve seats appropriately. Everything else he did by hand, himself, with a die grinder and a set of carbide bits, with his incredibly steady hands. He definately has less than $5000 into the car, include the car itself which he got on ebay for $200 (Dodge Dart of all things!)

The beauty of forced induction, is one can make gobs of power, without going insane with the RPMs. RPMs break engine parts. For his dyno runs, he didn't break 5000, not even once. With that many cubes and a fair amount of boost, you don't need to.

 

Better hope he has an aftermarket block frederic....or that thing is a ticking time bomb...esp if the tune isn't perfect. He'll split that baby right down the middle...

You want a 351 instead of a 302 because it has a longer stroke. They both have a 4" bore but the 302 has a 3" stroke and the 351 has a 3.5" stroke. The extra stroke gives you more torque and a more broad torque curve (more average tq across the RPM band).

Not to mention there is no replacement for displacement and the extra cubes come in handy.

 

do u think the 351 will bolt right in .or will i have to weld mounts.thanks oh and what about boost on my 302 ive just had it rebult ,

 

Yes, if some high rpms are realized it's a 900lb grenade. Tuning is not a problem as that's my participation But it has been proven again and again by my friends and I that larger, turbocharged engines that don't see wild rpms are _reliable_. My only concern with his build is there is blow-off valve, something I consider necessary in applications such as this.

Once he rebuilds the transmission, the car is going to be his daily driver until it snows. I'll report back at that time how reliable the engine was. Knowing my friend's right foot, the car will be used hard.

 

If your 302 is fresh with a quality rebuild it could probably handle up to 6-8 lbs of boost pretty safely and for quite a few thousand miles. I assume you're talking about a supercharger or turbocharger and didn't mean NO2. Will a S/C fit under a van hood?

 

frederic...what kind of RPM? The stock blocks are known to come apart around 700-750hp...most won't use anything but a dart or world block for 650+ w/o fear of loosing their investment.

302 is weaker...can only handle about 500-550hp.

There was a guy on the corral forums the other day asking why his oil pressure dropped when he pinned it...but was fine when off hard throttle...his block was splitting in half while it was running.

I only am concerned with your buddy's motor grenading on him after all the work and money put into it.
