5.9 Magnum Street Build - with dyno numbers

PRH, I am pretty sure you are correct. They even had an article on one with stuck valves and that it needed to be fixed with bronze liners, but then at the end of the article they say something like "oh, and it had an intake air temp sensor reading wrong so we replaced that too." Fuel injected truck.


Mine were bought bare and were new from Jeg's before they were discontinued. I had them finished off locally with parts I supplied, but wishing I had also added the bronze liners at that time. My fault.
