Cat 3306 PC engine want to put a 3306DI in its place.Straight swap? or not?

Replacing a 3306PC with a 3306DI is a pretty common swap in my opinion. It's a good way to make a little more power too. No computers to deal with. I have an st270 too, and it's something I would consider doing if I had to.

well we did that in a 627 scraper to pic up a few more HP to give her a little more bark. the fly wheels are the same safe mounting for the bell housing. the way the throttle hook up need a little work. that being said it's still waiting for us to get the rad back in to it. so un-tested

I wonder what the DI engine came out of. If it was a gen set you may have trouble with governor settings. If it was a dozer or grader you may have the power you want. In a Steiger St270 the 3306 was rated at 270hp. That turbo and after cooled. 270hp was pretty much max for a 3306.

There are some applications you can find a 3306 rated at 300hp. IIRC, the 3306 truck engines were rated 300-330hp max.

I stand corrected. I had an ST 270. Good tractor but running at it's max for it's size. Big frame small engine Steiger. All I'm saying is the pump has a huge effect on the output. Make sure the engine you're looking at put's out the power you want in the rpm range you want to run at. I ran my ST 270 pretty much right on the governor. Rated hp i think was at 2100. Cheers.
