Ive got a whole 12 valve parts truck to rape parts from to do this swap. The only thing I would need to buy is the fuel lines. My question is, do any of you that have completed this swap regret it? Im not so much worried about the performance part of the swap, which pump is faster or makes more power. I love the simpicity and reliability of the 12 valve but I stole the truck Ive got now (2000 3500 5 speed). I guess Im wanting to here the negatives about this swap. Thanks.
