Well zippy, need to go over to dieselplace.com, those guys with give you a good educating and ribbing. Also Being an HD truck, which has the drive inplace for high HP. And the comment about making power on the same boost, Just go other way on that gasser on 30 psi . Far as cost goes, Most dmax diesels run mid 13's on $800 programmer, me have spent $980 for high 14's(14.7). And when bought my truck, it was around $2000 cheap than any half-ton.(where I live) currenty, the most I have heard and seen is 795rwhp, 1300rwftlb on a duramax.

Just now I don't worry about trans, cause it will hande 450-490 hp, after that just a ATS co-pilot and good to about 600hp. With a half-ton, soon as the hp rises, got to start swapping driveline parts, basicly to HD driveline parts. So why not start with a HD

Currently I am getting 15 mpg highway and intown 12mpg, a guy I work with, with his 6.0 he gets 12mpg no matter what, so thats a wash.

Anyways, It be cooler if someone built a 4.8 to spin around 7500 or 8000rpm with a turbo.

there are many ways to go with these trucks, before i got this truck i was switching back and forth in my mind daily on what to start with. i was really thinking about a rclb 2500hd with a 6.0 and cuting it down for a short box. that wouldnt have been a bad plan at all but for what i want do i really need that monster frame?

a 8.1 in a RCSB or a diesel in a RCSB would be bad *** too.

one thing for sure, whatever it is it needs a turbo on it.

I think the 4.8 will max out at 600hp and 525tq. I think it will make more hp than tq because of its short stroke. I cant wait to see what the 4.8 will put down on the dyno.
