[QUOTE="elrodalexander73, post: 1270404, member: 16217"] Hmm, so head flow is an issue, I didn't know that the heads were that restrictive on a 6.4, I was reading on Rocken tech website that most pullers that need about 1200-1500hp with the 5.9s need approx 1200 cc of fuel to steadily make that kinda power and the guys who make big power with multiple chargers use up to 1600cc. I can see why a few have been developing the 7.3 with the P-pump set up due to ease of fuel delivery and available displacement. Unlimited's truck IMO will be a tough truck next year and they did a heck of a job. I just wondered why you don't see a whole lot of 6.4s yet, they have proven to be a solid platform when built right obviously. Oh and those moose tow mirrors can add up 200hp when fully extended btw.. [/QUOTE]
