Having recently completed my L and now driving it, I can relate to the decisions you now face. (See my "Project 51 L 110" in this build up topic) I went the SBC route. You could go Ford, Hemi, or what ever pleases you. If you're going that route, please note there will be clearance issues with the steering column and left exhaust header when installing a V8. Therefore, I decided early on that the column would go away and that led to the installation of the Fatman Fabrications Stage V front end. Stage V is the top end of their offering, but nothing says you couldn't go with the basic version. Fatman makes these front ends specifically designed for this era of International trucks and advertises that in their literature. But back to my main point. What ever YOU decide, it'll have a cost associated with it and can become a runaway snowball. You've already said you want to convert to disc brakes. Excellent up-grade choice. Your budget will determine what you end up doing. If you are looking at making the least number of changes to the truck, but making some up-grades, I'd suggest finding an inline 6 (Chevy, Ford, Mopar, etc.). And as has been suggested even today's 4 cylinders produce more horsepower and torque than the SD220. The drive train from a Dakota, Ranger, S10 or whatever are possibilities. And as Nikki has suggested heavily, diesel engines are currently a popular option. All will have their costs and set of complications to solve.
I don't know what the availability is for finding another SD220 block or complete engine. Some areas are better at producing them than others. Obviously, that would be the simplest solution to your current situation, but it will be a low RPM engine and can be modernized only so much. Others on this forum have added turbos to gain more get up and go. What it all boils down to is what do you want to end up with and how much you are willing to spend. The guys on this forum, both current and former, have done just about every version of the changes you are now facing and somebody(s) will be able to offer advise as you are confronted with a new dilemma. Make a plan and work toward that goal. You'll get a lot of satisfaction with each completed step and when the day comes you've reached that goal, you will be smiling from ear to ear and that will be one of the best days.
