I purchased a new 350HD for my 99 Tahoe that has 250k miles on the original motor. I was wondering if someone would take a look at the parts list below and see if there is anything I should add/change to it. I'm just looking for a reliable engine with similar mpg to the original. The main problem I had with the original motor was it drinking antifreeze. I would hate to know how much money I spent on antifreeze over the past 23 years. I replaced the intake gaskets twice, the second time w/felpro. It's probably going to cost me 10K. Now I am thinking I should have gotten this whole package for less than 15K! https://www.gmperformancemotor.com/parts/CPSLS3EROD6L80E.html
My main questions:
What do I have to do to have a reliable engine that doesn't drink antifreeze?
Is there a better reman transmission than the ATK for similar pricing?
It is my understanding ACDelco no longer makes the Lower Intake Manifold or the Fuel Injection Conversion Kit. What options do I have? I'm going to try to use the original Lower Intake Manifold if possible. Whats the best Fuel Injection available?
