Hey guys, so i bought a 7.3 as a project that has been on going for almost a year, lift, tires, 08 bumper/tailgate etc etc. So im almost to the turbo, injector, clutch, fuel air seperator, etc.. part, but i drove a 08 6.4 with a 275 tune and needles to say i was impressed!! but, the question is do i continue on the 7.3 and buy a set of 238's 38r a pump and others or will i be dissappointed.?? Im currently driving a 6.0 but live in fear of pulling heads so i just baby it.. i dont want a 6.4 if i have to live in fear of it blowing?? Thanks

both have been proven.. the 7.3 more so, but most dpf deleted tune 6.4's are solid as a rock, yet the 7.3 will cost more to build up, that being said 7.3's are easier and cheaper to repair unlike 6.4's lol so its all up to what you can afford really..

I love my truck but I would jump at the opportunity to get myself a tuned and deleted 6.4...... My truck with the mods in my sig made 396hp and 867 ft lbs. A tuned 6.4 can do that with just a tuner and deletes

I could afford the initial cost of either, but i also have to fix either myself.. i've seen enough 6.4's in the bay beside mine with complete short blocks.. heads.. turbos.. just scares me lol i reallly dont want to get into turbos or heads on a 6.4?? But the power is unreal and amazing throttle response. Will my 7.3 even compare to the 6.4, or will it be laggy and just blow tons of smoke? With supporting mods to get to the 450-500hp range. I'd love to drive one to see if i will like it..

Just remember to have a reliable 450-500hp 7.3 you are also going to have to build the trans as well... I'm not trying to turn you away from a 7.3 being as that's what I have, but dollar for dollar I think a properly maintained 6.4 with the right supporting mods would he wayyyyyyy beter than a 7.3

Do you have a power level goal? Cause if its just a reasonable goal of 500-600 hp then I would go 6.4 tune and delete it and your almost there already. If you just want to build something as big as you can I would probably go 7.3 just cause it will be easier and cheaper to fix like said above.

Only downside with the 6.4 will be the emissions. So you will be required to get annual inspections whereas the 7.3 was most likely prior to the OBDII port being installed. Which therefore makes it exempt.
