The duramax should have the usual chevy bell housing pattern. don't hold me to it. The cummins have an adapter. a block plate that a bell bolts to. There are a ton of stock and aftermarket adapters available to mate a cummins to ford chevy or dodge bell housing. Even to an SAE #2 which is...

The percentage of change you introduce into any one component if a mathematical function causes a corresponding change of the same percentage in every other component of that equation. I don't need to do a complex calculation to figure out what the change in rpm or speed will be after a gear or...

I went from 4:11 to 3:22... A 20% change in gear ratio resulting in a 20% change in rpm and a 20% change in highway gas mileage from 10 to 12.

32 divided by 35 = 0.914285714 1 minus 0.914285714= 0.085714286 round 0.085714286 to the hundredths place 0.09 times 100 to convert to percentage = 9% There is 9% difference between a 32 inch and a 35 inch tire. That will cause a corresponding 9% change in any other part of that equation 9%...

I think the 4bt might even be heavier duty than the 5.9 I've read there are 2 cummins six cylinders for pickups and medium duty trucks the 5.9 has cast in place cylinders and lighter castings while the 6nt has removable liners ans heavier castings for commercial duty. These cummins motors are...

Ford also had a brazillian made straight six diesel which can be found in alot of ISUZus, ford cabovers and f600-f700. it had it's issues but for most people was a good engine similar to cummins.

the 6.9/7.3 IDI is an entirely different engine than the powerstrokes The power-stroke didn't come until about 2000. You can identify one by the diamond shape to the ends of the vavle covers and the lack of any expternal injection pump or injector lines Powerstrokes have an internal injection...

On the 7.3 powerstroke or the 6.9/7.3 IDI they are both international motors They require an adapter to bolt to a ford transmission but I've read they bolt directly in place of any international V8 So I Assum ou could use any IH tranny or bell on one directly Here's where it gets weird Ford...

Expect to spend at least twice as much on buying a diesel. the advantage of a diesel is Doing a job too large for a gas engine while getting a little better mileage than a gas engine The diesel is a little more efficient at putting the fuel to the ground and the fuel itself has more btu than...

I don't care what kind of diesel you put in a 48 Chevy Willy I can spend 1/4 the money or less on a gas engine and beat you in the quarter mile. [P

Right Willy I didn't lump everything together in one comparison like that. I dumped a ton of info without much comparison but its largely geared to a 48 chevy half ton that's not likely to be pulling any 20,000# goosenecks to be more specific: Your not going to get the mileage out of a workhorse...

Actually I wasn't comparing to a ford diesel. The 7.3 or T444 isn't really a pickup engine. it's a mid sized truck engine in a pickup. The Gm diesel was designed for a light duty truck. A 1991 6.5 turbo diesel in a HD3500 chevy and a 12' flatbed will beat a dodge 3/4 ton pickup with a 5.9...

basically with a diesel engine the foot pedal doesn't change the air or the fuel it changes the idle speed in the governor and the governor makes the timing and fuel adjustments to bring the engine to the new idle speed.

Ok what I meant by max mileage and sweet spot.... The fuel curve on a diesel is linear up to the sweet spot when you step on the pedal it's the advance that speeds up the engine and the fuel just keeps up with the advance once you are at max advance.... the fuel over runs the advance and gets...

Oh yeah.. And automatics are easier on things like head gaskets, head bolts, cranks, bearings etc than manual trannies. In your truck you can run a stock 700r4 behind a 6.2 or 6.5 no problem diesel torque converters- with Gm there is no diesel torque converter per se. behind a diesel GM used...

if you have black smoke coming out of your tailpipe you're wasting money, your truck needs a tuneup, and your not driving it right. [ddd
