Early 5.7 diesels sometimes broke the crankshafts. The engine and the Stanadyne pumps are made for each other and there was not a lot of room left to push more fuel. They were designed for efficiency rather than power.
Diesel works!! What next?

Carson, I hope we have not dashed your hopes. I like the advice above on uncorking the intake and exhaust. Maybe a 403 is the future right answer if these mods can transfer over. You already have the Hydroboost brake system, so if you go to gas, you can go big on the cam and still have good brakes.
And the great thing about G-Bodies is the engine bays are so big, they’ll swallow just about any engine you want to shove under there.
In all sincerity, I'd say drive it and enjoy it as-is, do a few bolt-on and tuning upgrades that you can. Like others have said, the 5.7 diesels were never designed with performance in mind. The 6.2/6.5 swap into a G-Body has been done, and is probably the better way to go if you want to do any sort of performance upgrades.

I read that the 5.7 diesels lacked a water separator, which is somethig all diesels need. The unfortunate consequence was that steel components within the injector pump subsequently corroded over time and progressively starved the engine of fuel (power) and made them even more gutless. Did you have your injector pump overhauled? Consider adding a water separator.
Those engines have a small following. There are some folks out there who have learned how to overcome their design flaws and make them run reliably. The google search is your friend.

That's very good to know! I will be sure to do that.
I will enjoy my ride no matter what, just seeing what else I could do to her 'cause that's the fun part about cars. I agree about the intake and exhaust, I'll see what happens. Who knows maybe someday I'll get a different engine but for now I might as well enjoy it as it is.
I haven't had the pump worked on, that might be something to do in the near future as well as the water separator.
I did my LS swap for tree fiddy.
I know the gear ratio is 2.29, but I need to double check what transmission I have.
