Hi this is all new to me i am trying to find out some info i have looked on the net but no luck.I am trying to find out what bhp is a ford 5.0 v8 its in a econoline are these engines all injectors.Its a 1987 are the engines any good or are the engines with the carbs better.Can you fit a carb to the engine.What mpg do they do any help would be greatfull thanks forgot to ask is the block a 302

 

An '87 Ford truck 5.0 would have been rated a 185hp and should be EFI. These motors are very well built and are capable of quite a bit more power with some simple and inexpensive upgrades, and in no was is a carbed version superior.

 

In a van, nothing you can do will help matters much on a 302. A swap to a 351W will do wonders. It needs more torque, not more HP.

 

302 was built to rev but they lack bottom end torque which you need to get a truck moving..There is no replacement for displacement..

 

Except forced induction.

But assuming that's not an option for cost reasons these early EFI motors were badly smothered with tiny cams and restrictive exhaust systems so there is some torque and milage to be gained with upgrades in this area. I doubt an E150 is any heavier than my xcab 4x4 F150 with a fiberglass cap on it and I have seen significant milage increases with longtube headers and a cam change to the stock 5.0.

 

The thing is, he can get the same mileage and increase the torque by swapping to a 351W. The mileage difference between the two is nil.

 

I imagine getting hold of a 351W and the little ancillary parts for the swap in the mother country is a little difficult, so upgrading the 302 is probably more practical.

 

There's nothing really different other than the exhaust manifolds and that only the passenger side, if he can get ahold of one, that's the way to go.

 

I certainly won't argue that the 351 is a FAR better truck motor, I've had both in my truck and there is no comparison.. the 5.8 will bitch slap the 5.0 and tow it around backwords.. and milage is pretty much the same too, but it may be a more work that the OP wants to do.

 

Hi and thank you for the help.I have just logged back on and i didnt think i would have had this much help.So i will forget the 5litre how about a 460 ci engine i have the change of one on gas lpg.Or a 351 winsor which is the better one and what mpg should i get.Thanks

 

Depends on how much it costs you to feed a 460 on LPG, vs a 351W, the 460 gets about 30% less MPG on gasoline as opposed to a 351W. My 95 E150's best MPG was 16, most of the time it was around 12-13 on the highway. And that was an EFI roller cammed 351W with a 3.55 rear and an E4OD transmission. I had a friend that had a 92 E150 with a 302/AODE/3.08 rear, it's mileage was dead even with the 351 in mine. You will just have to work out the math to decide, I know things are much different over there as far as fuel prices go. Here in Louisiana, regular gas sells for $3.35/gallon. CNG when you find it is around $1.90 (per GGE). LPG is much more expensive than CNG, 5 gallon (portable exchange) tankfuls run about $3-4 per gallon. Never priced it in the 100-200 gallon tanks. We're in the midst of an oil boom in several states right now, so hopefully crude oil will drop like natural gas did a few years ago. CNG is so cheap they're talking about exporting it over to your side of the pond, instead of 10 years ago when they were building import terminals (that never got used)

 

Regarding Baddad's last post,

Can't they just run the CNG import terminals backwards?

Gasoline works out to about US$6 per Imperial gallon, or about $4.85 for a US gallon here in British Columbia.

 

CNG import terminals simply move the super cooled and compressed CNG from a CNG ship to CNG storage tanks. To export it, the natural gas from the pipeline has to be super cooled and compressed to liquify the gas. It's cooled to something like -268*F to compress and liquify it. To use it in a vehicle I think it's somewhat less than that.
