Well I kinda see his point... but he could definately be less of a dick about it...
This actually looks like alot of fun (well to me because i don't get to wrench enough) Looks like you got yourself a good interesting project.
So the 6.2 will bolt up to your 6.5 tranny and everything? The 6.2L is a non turbo if I'm correct...? It is going to fair well with the turbo on it?
yep. the 6.2 will bolt right up to my 4L80e.... even going to use my 6.5 fuel system so I don't have to change the computer for 1 that just runs the transmission.... (although if I had the money and time to track down the parts I would run the military version of the pump used on mechanical 6.5T from the HMMWV, has bigger plungers)
this one is Naturally aspirated, I will be using 6.5T head gaskets (as the heads are the same.... infact the 6.2 has bigger valves)...... due to the crack I will be limiting the boost to a max of 10 psi and a sustained of about 6-7 psi..... but others have run 20 PSI on a 6.2 with 6.5 head gaskets with no problems. Will has a banks turbo'd 6.2 running 12 psi with no ill affects..... I have been following a build on a 6.2 running 40psi boost and his goal is 60 psi for a sled puller...... his engine is highly modified and is running 16:1 compression.... a stock 6.2 is in the 20.5:1 to 22:1 range (this is why a nastily aspirated 6.2 gets 22-26 mpg in a 3/4 ton 2wd).
truthfully I have no desire to put in a Duramax .... The IDI mechanical fuel system is more reliable and IDI will burn any old crap you can put in the tank......
now if I had a cherried pre '92 Crew Cab Fatback with no rust and a flawless interior I would be looking at maybe a GEP P400 optimizer (390 hp, 550 ft/lb torque)/ Allison 6spd or a first gen Duramax/ allison 1000.
