Let me start by saying that I love my International. It is a real truck with a real truck strength and ride.
Now, the only thing that I don't love is the lack of power that the BG241 straight 6 has to offer in my truck. I feel that it isn't just the IH power but my combination of tire diameter and gear ratio. The factory put 6.17's in the rear axle. With stock size tires it would realisticaly top out at about 55. With the 4.10's and 36" tires it would easily go much faster but it would have to be down hill with the wind at my back. It struggles at normal driving to keep up with traffic. All this without a load.
So out of necessity I have chosen to swap out the 6 cylinder for a 1974 Cadillac Eldorado 500. It has an Edlebrock intake with a rebuilt Rochester carb, new timing gears and chain, new fuel pump and a new water pump.
The transmission is the Cadillac Turbo 425 that has been freshened up. I may put in a shift kit before I install it.
I chose the Cadillac for all it's torque. With 525lbtq it ought to scoot the old IH pretty well. I use the truck everyday and will from now on. It is my work truck and I haul lots of weight in the bed and while towing. I really need power.
I hate that I have to remove the six but I feel that this is the right decision for me and my company.
Here's just a teaser;
I will do a step by step with pics for those who are interested. My next step is painting the engine and installing all the accessories.
Pic update Wednesday, I hope.
