Quote: Any year 6.1 is a win. I have read the early 03-04 5.7 block were thicker walled. An 05 5.7 is as good as any other 5.7 but it also has the benefit of no plug wires and no mds coming from a truck.
This engine is coming out of a truck so MAYBE I should continue to look... what does it take to kill the MDS... to my understanding the lifters have a slot in them for the solenoid to push something in
You just need 4 MDS delete plugs from a 6.1 or HD 5.7. If you leave the solenoid in the block but unplugged, it will do weird things. Use the plugs and be done.
