6.0 Gas to 5.9 Diesel

I have a 2005 Chevy Silverado 2500HD with the 6.0. My question is, is it worth swaping in a 5.9 Diesel? how difficult is it? Mind you the 6.0 wont be leaving the truck for a while, i just thought about this recently. And i didn't mean to put this question under the Suspension catagorey either

I am sure it has been done but I would not want to put the weight of that 1100 lb motor on front IFS. Logically if you want a oil burner, swap in a Dmax or even older 6.5 and it will basically bolt in with little fuss and both weigh a good bit less than CTD too.  

We'll the truck has a Solid axle up front i did a 4 link swap and coilovers but you think a duramax would be better, i'd rather have a duramax but i figured most people swap cummins in more than a Duramax.

dont waste your time on the 6.5, the duramax might bolt up easier but its gonna be an adenture wiring it all up even if it is a chevy, the easy swap would be a 12v cummins, no wiring and PLENTY OF POWER POTENTIAL or if you want the ease of electronic power adders go with a 24 v cummins then you will have same electronic adventure as with duramax but it will make power easier by electronic tuners and such, btw the cummins is much easier and cheaper to build power with than with a duramax or powerstroke, also nice truck i love seeing modern chevy hds on solid axles  
solid axle chevys cant be beat

CTD has a much more limited effective RPM range (the more you boost it the more limited the range is) than Dmax and extra weight of it is never a asset. Also 6.5 is not a bad engine for what it was designed for and not much to hooking one up either. While is does not have boost potential of others it does have a far wider usable RPM range than the others too.  

Thanks for the Info and cool comments about my truck , i was thinking more or less on the 12 valve cummins but we'll see how things go, i might just go with an 85 CUCV Chevy K30 with a 6.2

The 6.5 is actually a improved 6.2 with more displacement and stronger block and thicker heads to handle more boost and HP output.  

yea i figured i like the the 6.5 it was good for its time if the Chevys had solid axles when the 6.5 was offered id hunt for one of them but the 6.2 was offered in the SFA Chevys.

Bolt in would be same though and if pan is wrong on 6.5 I am sure it could be swapped with a 6.2 pan and pickup.  

May I ask why? What's wrong with the 6.0?

Theres nothing wrong with it, this is just research for when the 6.0 decides its to tired or explodes after to many miles.

I have a different backup plan here. I have a complete TBI 305 on a engine stand that one day I plan to rebuild with higher CR and possible stroked as well to a 334 as a backup replacement for my two 350's Given fuel price trend though I will likely just bore it .030 over to a 312, use a cam with more lift optimized to lower and middle RPM power and bump CR to around 11 to 1 for 93 octane fuel, more power better MPG too and net result should be same or more power as stock 350 using less fuel doing it. If I decide to make it a E85 only engine, I will increase CR even more as it has a octane of around 104 to 107 and even higher CR will improve efficiency and power on E85 compared to that of a lower compression engine that tolerates 87 octane too. Using E85 in a Flex Fuel engine that has 9 to 1 CR or so to tolerate 87 octane too is really a big waste in my book.

So basically your saying keep it a gas truck????

Yes but one with a modified engine (if you swap or rebuilt) with higher compression and better efficiency to adapt to fuel options of future.  

I like the potential of the 6.0! I know it will never reach the potential of a tuned diesel without getting drastic, but think about this: Look what the Cadillac version is rated at, off the showroom, and look at the gas mpg! My mother has an '08 Escalade and averages 18mpg. That's not much less than an empty diesel, and on 87 octane.
