Encourage them, bring ideas how to do it.

I would LOVE to do a big block--if for nothing other than the sound a good cammed big block makes. I saw a nice 8100 at Turkey Rod Run this weekend for $4500. It definitely got the wheels turning.
Torque is what we need to get this heavy trucks moving, and a big block will provide that in spades. I say go for it!!!

You have a horrible attitude. I can understand wanting to further a sport that you love, but the guys on this site are mostly concerned w/ 1/4 mile performance. There's nothing wrong with pulling, but there's also nothing wrong with NOT pulling.

You are confirming what I was thinking all along about the truck world here. Just a bunch of transplanted Car guys that want to use their trucks as cars. Even less work would be to make a camaro go fast, since thats the theme in this thread. Since most use their trucks as a cars. Besides if you are decatied to making your truck fast for the 1/4 only, don't buy 4x4!! Also you know so much about the cost of building a 8.1, please enlighten the rest us with a Itemized list with costs.
Gm say to pull trailers, when you pull one in truck pulling!!! Most of the time its a 44,000lbs weight transfer sled. Here one of the top duramax guys in US http://duramaxracing.com/ Also has lots of vids. Also he drag races and pulls with the same truck. Currently cut a fastest 1/4 of 11.9, hook up his trailer goes to truck pull event. Unhitches and pulls, hook trailer backup drive to another. Kinda makes your half-ton feel like crap. I know it does me, I am just goin it keep modding until its there.

Way to miss the point... I don't really care what your assumptions about me or my truck are. You know why? Doesn't change what I do to my truck one little tittle. It changes my opinions about swapping in an 8.1 even less. 572 long block? Hmmm. Now maybe we're on to something.If you are sure you can build your 8.1, great! Go do it and go faster! In the end, you're the only one who *really* cares -- its your truck. If you want to 'use your truck the way it was meant to be used' great! Go get it muddy and twist up some driveline parts.
In the mean time, I'll make my truck run 10's. I'll keep my AWD (which should give you a hint about what MY truck was meant for) for drag racing, and not worry too much about traction problems. And in the mean time, I'll have a helluva a good time burying the local RWD guys on the street.
The question is why people don't put in 8.1s - it will fit and make more power. I think that's been asked and answered. And surprisingly to some, it has nothing to do with truck pulling.

Darn it, I keep forget that my view point always worng, just your are always right 
Wish I could remember that.
mahle has forged pistons for 8.1 in stock bore .010, .030. oversizies. Plus forged cranks are being made and developed. And the rods are already forged.
have few of these and chill

I bought an 8.1 today...i have other motors but learned the computer in my truck will interface with the 8.1...i am currently researching heads because i want aluminum...as far as stroking it...that only consists of removing/clearancing the block for crank & rod throws...i have not decided on an adder yet, but changing the pistons, crank, rods, heads, & most of the valvetrain is going to happen...the bed is off my truck and the process has begun...i expect to spend 15k on the new & improved RST...i also expect over 650rwhp...i really enjoy having & building things no-one else has...thanks for your support

yes i did & i appreciate your info...thats the stuff i was hoping to get when i originally posted...i love power too...i also love the way a hot BBC hits as it heats the tires....i'm not concerned at all about fuel mileage or smog laws, there are ways around that...my experience with turbos has come thru some of my outlaw friends (mostly thru David Wolfe), Grant McCrary, & Scott Winsett, all say the small motors like the turbo better...especially big bore/short stroke...please feed me some info, i've never done a turbo before i'm an old nitrous guy with some blower experience

Step out of the box....
If the original poster has the BB experience he says he has, who's to say you can't do a big Hp setup in a half ton that would work. A 2500 chassis would be better suited but who knows what could be done.
You only need to look at marine stuff to see what can be done with BB's let alone drag car stuff. I don't think he was talking about 1200hp Sterling marine or Cheif marine engine with a BIG blower sticking out thru the hood, in a truck.
Look at ASM's web site and see what they have for marine big blocks. Some of this has got to be transferable to automotive by an experienced builder with deep pockets, power to him.
The guy got slammed pretty hard and slammed back but is still posting which is great.
It would likely be more cost effective to do a F/I 408 but who cares, if he wants to do it let him do it and we'd all learn something.
Power to you Byran.
Did I mention I've got a BB in my boat and Gm has never built a finer engine.
www.offshoreonly.com check the classifieds, not a great time of year for marine stuff, but nice, none the less
IMHO DAVID
