6.4 lift or 6.7 replacement

[slc6oh]

Been reading my dick off, pic; links: all broken, no real good reports or write ups.

Assuming healthy factory pump, with slight possibility of 190/30s to go with my t4, s362. ..


Which is best?

Install/performance/reliability.

Opinions???


(DD regulated return is on truck)

Good success has been had with both setups. Do you plan on increasing air and fuel at all in the future? I'm going with a 6.7 pump feeding the back of heads.

Its got a 362fmw on it, i doubt ill ever go bigger.

Long term, daily driver, weekend tow/play reliability is #1

But if i can safely put a hot tune on and make 550 or so, thatd be cool.

A 6.4 as a pusher pump would probably be just fine. Personally I'd go with a sump a 6.7 pump simply because it makes for one less component that could fail.

I'm with ya been looking into this so much I'm tried of reading sometimes. So a sump and a 6.7 pump is good for that setup should be a great route for my 175/30

6.7 keeps up with my 205/100's and doesn't skip a beat.

6.7 pump FTW.
