I don’t know if anyone has ever discussed this scenario. Since building a 5.8 is so expensive and if you destroy the block you are now out thousands of dollars, so I had this thought. One could buy a 5.4 and build the hell out of it and pull there 5.8 set it aside and probably save thousands of dollars going that route. Am I thinking this right, you wouldn’t be leaving that much power on the table as your only loosing .4 on the engine with all else being equal, boost porting etc. Or am I missing something here. Just a thought I had and felt like throwing it out to the people in this forum that have way more knowledge than I do.
