I want a Superduty Diesel

[DaveBen]

They do have a head bolt problem, in that the design of the motor did NOT use enough head bolts. The head gaskets can blow if you run a programmer and don't watch your boost gauge. ARP head studs will cure this, but it is a lot of work to pull the motor to do the studs.

I know you don't want one older than a 2005, but if you could find a 2002-03 with the 7.3 engine, you'd also get a good truck. However (from what I've heard and read on this site), the later 6.0's (2005-2007) were also good engines.

my truck is an '03 with the 6.0 and I haven't had a problem with mine. I think maybe it might be some guys throwing a ton of aftermarket HP at an engine without knowing their truck. I have done moderate upgrades, with moderate increases, and haven't had a problem

That's good. However, according to comments that I've read on this forum and other sites, the 2003 and 2004 6.0 engines weren't as good as the 2005 and 2006 models.

Anyone else have comments on which superduty to buy? what are the differences between the 250 and 350 in transmission, rear gears etc...

 

[DaveBen]

Transmissions are the same. Springs are about the only difference. There are a few others, but nothing major.

I think some people are spreading bad information and WE are buying it, lock - stock - and barrel. 14 mpg is good for a 6.4!

Once mine broke in, the mileage is about 14.4 per gallon, hand calculated. Does a little better on a trip, a little worse towing. Same as any truck.
