General consensus doesn't know crap about the v6.
The block and heads are the same as in the 4.2L F-150 V6. All you have to do is swap out the rotating assembly. If you overbore the block you can come up with 4.3Ls, and if you modify the crank, you can come up with 4.4Ls.
I wouldn't recommend the offset grind on the crank though.
Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.
