there's a lot of die hard 6.4 guys on powerstrokearmy.com Not too many on here. What are you looking to do? They've taken 6.4's farther in the last two years than 6.0's have ever gone. 1000rwhp on fuel only has been achieved recently too. Triple turbo's, single turbo's, prochargers, CP3's, etc... it's all been done at this point and only going forward! The 6.4 is here to finally give Ford some credit!
