A guy that runs a diesel shop here in Spokane dynoed a little over 300 horses with a 6.2, I know he has propane injection and an hx40.

Look up Davis Diesel and ask for Jeff if you want details on the setup.

I am one of those people who bleave that the factory did a little better job on mine and that there is no task too hard to handle! I have nothing to ask you or any one easel but not just to say you Esperance makes all 6.5/6.2s bad well that just stupidity not fact
FACT MY STOCK 6.2 before mods with (highway gear) had no problems hauling my z71 with 5.7 at 70 mph with no problems unlike (I CANNOT get my 6.2 over 1,000 and that is pushing it hard ! ) chew on what your own a pos ! Lol great sell it so someone who knows a little bit more about their truck!
The 6.2 and 6.5 from 1992 are all the same the bore is it the problem is they kept the crank too throws boost and too much fuel at it and yea it’s a time bomb! Even under full tow mine will only puff a little I have had it on a dino for 3 weeks straight to know what I know now!
Yep I broke it too but only mudding a turbo and a 6.5 ip turned 3/4 a turn! So yea they are WEAK compared to a Cummins!

SO I SAY GO BACK TO SCHOOL! COME BACK WHEN YOU HAVE NEW INFO!
Its a chevy not dodge (mild power) not balls to the wall power house !

You quoted me but I did NOT say they were all weak ????
I said the 506 Blocks were which is a known fact. I assure I have been to diesel school and have worked on them for many many years.

I call BS
I have a 1992 6.2 n/a I custom built a 4" exhaust 7" tip turned up the fuel pump and added a 6.5 turbo intake to delete the erg and converted to amsoil synthetics
it added tons of power and great fuel mileage

Calling BS to what ? that a turbo addition is not good for the 6.2 ?

MTL, you misunderstood.....

I have owned many 6.5 GMT400 trucks and everyone of them could run hot and high egts. I CANNOT get my 6.2 over 1,000 and that is pushing it hard and even towing it never has gone over 200 although I am running a HO 6.5 cooling system.
Anyway my elbows and hands hurt(damn tendonitis)so chew on that for a bit and ask away.

Ok, MTL, I do believe you misunderstood Ace's post. Read it again, with my paraphrasing.

"I have owned many 6.5 GMT400 trucks and everyone of them could run hot and high egts. I CANNOT get my 6.2 over 1,000 [egts] and that is pushing it hard and even towing it never has gone over 200 [degrees F] although I am running a HO 6.5 cooling system."

"Anyway my elbows and hands hurt(damn tendonitis)so [think about] that for a bit and ask [questions]."

His "chew on that" was not meant as a "stick that in your pipe and smoke it" sort of phrase.

Aces, correct me if I'm wrong.......

To be honest I don't know what MTL meant. I was agreeing that a 6.2 can be built.

I don't think he knows what he meant. He made two statements at the top, and then contradicted himself at the bottom.

i built a 6.2 in a K5 blazer, i used short injectors, and all the turbo parts off a 6.5 turbo moter... and it would out run my 95 Z71 6.5 turbo truck (that i had also heavly modded) any day of the week... wish i had kept it.. 24mpg was nice:argh:

Banks still makes turbo kits for the 6.2. My dad put one in his '83 Suburban, and was getting up to around 15 lbs. of boost, and a WHOLE lot more power! Actually, the 6.2 with a banks is a considerably higher performance engine than a stock turbo 6.5. As long as you have the tougher, military style 6.2, there's no need to worry about blowing anything up. these are ridiculously tough engines.

You could buy new injectors, turbo it, fuel pump, lift pump. But if I were you I would just buy a 6.5 they are easier to make more power from.
