did that guy on ebay have a f-150 box and cab and mount it on a f-600 frame?! that this is frigg'n awsome, makes my truck look like a toy

i wonder if i could do that to my truck....na nvmd, i still love my 93 f-150 300-i6

 

the lower tourque rating may be deceptive. If all the peak torque is where you need it, it is better than if you have a ton of torque out of your usable RPM range.

 

DeGideo, I just wanted to clarify regarding the book, "Ford Heavy-Duty Trucks 1948-1998 Photo History." There are a lot of specs in this book, but mostly in the text. Things like weight ratings, engine sizes and power outputs, some gear ratios. There are a few lists of prices and options. But for someone like me who wants to quickly compare across all the different years and engines it would be difficult to fish all the info out of the text. Also I don't think there was even mention of the 300 I6 (one reason I bought the book was to see what it had to say on that). Still a great book and will help fill the gap since the 1978 cut off on "Ford Trucks Since 1905."

Hey, I just bought the book "International Trucks." It is in the style of "Ford Trucks Since 1905," but goes up to 1995 where it is Navistar International. I see in another of my books where Navistar makes a "powerstroke diesel." I wonder if Ford's current power stroke diesel is made by Navistar?

 

In 1983, Ford & Navistar began a working relationship. The first offering was the Navistar-sourced 6.9L(420 cid) V-8 diesel. In '88 it was enlarged to 7.3L(444cid).In mid-'94 the direct injection version of the 7.3L diesel was created to Ford specs by Navistar. I think both Ford & Navistar engineeres worked together to create the Powerstroke diesel. Navistar(now International again (???) ),has been using the 7.3L in their medium duty trucks for years.I think they call it the "T444",or "444T" diesel.Ford has also been using the Powerstroke diesel in the F-650/F-750 line for the past few years.

 

Thanks, great info. Makes the International Trucks book I bought even more relevant, knowing that it ends up with a Ford truck connection.

 

I would stay away from any of those old industrial Ford engines smaller than the 429 as they are major gas pigs and don't produce enough power to pull the scum of of your morning porridge. There is one of the forestry companies here that I work with time to time has a F-700 Ford 5 ton flatdeck with a 429 the truck will burn 45 gallons of gas in one day with no problems at all. The truck is so frigging underpowered its pretty rare you get out of the low range on the rear axle when the truck is loaded.

Nothing beats diesel power for any truck that carries or pulls heavy loads gas pots in a MDT is just plain dumb.

 

Hey TallPaul,got some more info. for you on the medium duties. I just received the 1991,1992,and 1993 Medium Duty/Heavy Duty Truck Specifications Books which I had recently ordered.The last year for the 370 engine was in 1991 models,wearing a 2V carb,and rated at 164 horsepower@3,600rpm.Looks like my theory was right....once Ford added EFI to the 429,they offered four(not three like I thought)versions of the "7.0L EFI" starting in 1993 models.The first year for the EFI429 was in 1992 models.The EFI429s featured 8.0:1 compression,and had 236(net) horsepower@3,600rpm (with an automatic tranny),231@3,500rpm (w/ manual tranny),and 358(net) lb.-ft. of torque@2,800rpm.The EFI429 was also available in an "economy" version : 216 (net) horsepower@3,200rpm,and an LPG version rated @218 horsepower.The 216 "economy" version & the 218 LPG must have been first offered in 1993 models. In the 1992 spec book,it only lists the 231/236 horsepower engines.Basically,the EFI429 with 216 net horsepower was the 370 2V's replacement.

 

Fuel injection must be costly to add to an engine for production, which would be an incentive to kill the 370. With fuel injection I would expect the 429 fuel economy would have improved enough to make it a good replacement for the 370.

 

Yeah, I would think the EFI429 would have had better fuel mileage than the 429-4V.I wonder exactly what Ford engineers did differently on the EFI429 vs.EFI460?I've seen both engines,and the intakes/throttle body assemblies look alike,but I would think some changes would have been made for use in medium duty trucks. The EFI429's camshaft is a bit more mild than the EFI460's.I actually thought about using a EFI429 from a junked F-700, I had a chance to buy,instead of a EFI460 for my 1990 Bronco engine swap project. I didn't buy it because at the time I wasn't too sure about the two engine's differences/specs.I know you can stroke a 429 to 460cid,but why not just buy a 460 engine to begin with? Still,when all is said and done the 429 must have had some merit in the medium duty truck line.Why else would FoMoCo spend corporate dollars to add EFI to it?

 

If the 460 is a stroked 429 I would expect more torque at a lower RPM from the longer stroke in the 460.
