8.1 performance parts...where are they???
ok this question has probably been asked to death, but i'm still hungry for all the info i can get. Gm's 8.1... what is there for performance parts and what have people done to it. my 93 chevy is gettin tired and she needs a replacement. I want my next truck to have some spunk to her... i've seen so many 6.0s get up into the 600hp range... but i can't bear to go to a small block (the fuel doesn't bother me). All I can find is 6.0 parts.. does any one know where i can find parts for the 8.1. I've seen marine 8.1's get high, but those aren't all that street legal. If i have to i suppose i'll drop down to a small block but as a last resort.... Ideally i'd like to drop an 8.1 in2 a 2500hd ec sb and sell off the 6.0. Go w/ either a intercooled whipple or procharger cuz i'm not 2 sure if i want twin screw or centrifigal. The allison is just not a performance tranny and the 4l80E has more successes under its belt than i can count. i'm guessin $50k w/ truck and mods after i'm done....ouch i guess thats y i've done nothing but work my tail off for the past 8 yrs and live like a granny

No there are quite a few parts:
Cams, headers, Intakes, MAF, Programmers, EDIT works with it, Whipple has a twin screw supercharger, you could easily get the heads ported too.
The Allison is a badass trans. If you tow with your truck you'd need a Multiclutch converter so you won't slip in OD. http://www.suncoastconverters.com/index.html and www.atsdiesel.com has them. They will take in excess of 450+rwhp and 800+rwtq with that Multiclutch converter and a valve body mod.
I am gonna flip my Z71 in ~October (I'll have enough to pay in full) and buy a 2500HD DMax/Allison 4x4. Check out www.bullydog.com or www.duramaximizer.com or www.atsdiesel.com for performance. You have programmers, propane, 4" exhaust, NO CATS from factory, nitrous, and 20+mpg on the freeway in economy mode with the programmer...

Re: 8.1 performance parts...where are they???
I have two 8.1s that I've been modding. This first in in a Suburban. It has a Whipple supercharger/intercooler, Volant induction, TOG headers, Direct Hits Ignition and custom programming. So far it's run 14.5 @ 92. The second truck is a Silverado HD. Mods for that one include a Volant induction, ported throttlebody, TB spacer, TOG headers, Comp Cam, custom programming and electic fans. I may be doing the heads in the near future.

Remembr the 8.1L is just a Big block chevy any od the mk6 parts will fit it there are the edelrock AL cylinders heads and cams galore + the usaul headers exhausts etc. there isn't as much stuff developing as the 8.1 is at the end of its life cycle.

No ****? I thought this was a redesigned motor like the Gen III motors! I heard it was just an increased stroke 454.
Why is it at the end of its life cycle?
