Should I just throw new rings/pistons and give it a quick hone. Then put it back together with studs and everything? And then get this 6.9 running and sell the 6.9 engine? I think now is probably the best time. I don’t feel like doing a huge rebuild on that 7.3 and it ran perfectly fine before hand. What do you guys think.
It's really up to you, but here's how I see it. I think that, in the future, you'll probably want to try to get more power out of the engine than it currently has (had?) now. I know you were happy with the way that it ran with the bigger turbo on it. It's only a guess, but if you do decide to go for more power in the future, you'll be kicking yourself for not installing the 7.3 when you had the chance. I've said it before and I'll say it again. Take your time and build the truck that you REALLY want. Not just what will get you driving it the quickest. You've already done so much upgrading to the rolling chassis, it would be a shame to throw in an engine that you will want to replace in a couple of years.
Before you decide to hone and put new pistons in, make sure that there's not too much wear in the cylinders. If there is, that may make you change course and run the 6.9 for now and build the 7.3 up for future use. Of course you want to use studs too.
Probably so.
