7.3 for a 6.4

[snwbrdngrx14]

I have a 2001 7.3 I found a 6.4 I like but was wondering if selling my 7.3 and buying a 6.4 would be worth it. My 7.3 has a decent amount done to it and I love the truck. Kinda decided to look around for a new project and I was wondering if the 6.4 is really worth the investment ? Also what would I look be looking at performance wise and also has Anyone had any major problems ? Any advice would be awesome

It's an awesome truck as long as you do the dpf delete. If not then I would keep the 7.3 because with the dpf on the truck gets pretty horrid gas mileage and my truck started smoking blue when in regen so I deleted it and haven't seen blue smoke since. No real major problems. Some of the early trucks has radiator issues. Head gaskets are still the weak link but I don't think it's quite as bad as the 6.0. Actually alot better since the stock heads are holding hot tunes as long as they aren't beat too hard on. I'm running h&s hot damn 300 which is dyno at 580hp "says h&s" which is alot more than the 6.0 stock heads would hold.

Thanks for the info, I was deff thinking of deleting the egr dpf and other stuff, I live in Pennsylvania and I'm not really sure how my h they check emmsions. Also your truck looks pretty mean

only had my 6.4 for a week, 550 miles so far and I love the truck alot more then the 7.3l, the mileage is not good,(but the chassis crewcab dually with a flat bed weighs about 9300#'s), my deletes will be here mon or tues. but the interior is way better than the old. and the fact I can hear my 2 yr old asking questions in the back seat without turning off the radio and lefting off the pedal is a big bonus. Also the truck feels just as quick stock as the 'ol 7.3 did on the PHP 80DD setting.

I have a 4" exhaust and gtp38r so I personally love the sound but I understand. The truck I'm looking at is a single cab long bed with 6 speed and 13k miles for $30k so I didn't think that was to bad of a price for an upgrade
