AFR 225 72cc...and I'm running an AlkyControl meth injection kit now. As to cam, in hindsight, I should've changed cams during the rebuild, but as I stated early on LPE thought it would do fine since they used them a lot in their 383 pkgs. I bought a Speed Inc. blower grind and will throw that in eventually to see what it does.

 

dam man it shoudl make more than 500 thats a trip. how many pounds of boost are you running? I know the 122 likes a lot more boost it shines at about 12-14 psi.

is the cam like gt2-3?

 

Does it really shine up there or does it just dyno well?

 

sorry 10 psi is when it starts to wake up. Then again thats on the front driven set ups like on our tbss and vetts and gtos.

Im just wondering how many psi boost is he running.

 

I agree 110%...it "should" be well over 500, and I have been making that argument.

Engine components, gearing, tires, boost...EVERYTHING, before & after, is in the first few posts of this thread. LINK

 

If i'm looking at this right you picked up about 2mph and .2 going to a 383 and a 122 over your 5.7L and 112?

BTW, I have an 02' 2wd Tahoe now and I'm slowly picking away at it. Do you have any pictures of yours?

 

You are correct sir...hardly anything. Pics from yesterday...I have a bunch more I can email you if you like.



Between rounds...





The last run (#4) before it popped...single tire fire!



And the grand finale! (Its good to have friends!)

 

Hey Zippy...how's your Detroit Locker for "everyday driving"? Noisy, clunky at all?

 

It is a little bit clunky. You have to kinda get used to it. If you change how you drive just a bit you won't even notice it much. I went with that because they are pretty much the strongest thing you can get without going to a solid spool. Because of me alot of my friends have used them also. We had one in a friends 99' Tahoe and it was great. The downside is when you feed it throttle if you are turning just slightly. The rear end tries to steEr the truck. I think that one had more problems because the bushings in the leaf springs were getting worn. The Tru-Trac drives alot better and is almost as strong, but the Detroit Locker is stronger and if mostly what you do with the truck is run it hard it's worth considering. Either one along with a girdle cover would be a good choice. If you haven't had the Auburn long you may be able to get one on the trade in program fairly cheap. If you are planning to go alot bigger on power yet you may want to eventually shop around for a 14 bolt 9.5" from an Avalanche/Suburban. The new body style trucks use them for the versions with the L76/Vortec Max type option and they should be a direct bolt in.

Your truck looks great, is it lowered any?

 

As my wife does drive it on occasion, I don't want alot of odd noises and "pushing" that the Detroit would most likely give it...guess I'll aim for the TrueTrac then. I'll also do a quick search for the 14-bolt, but unfortunately I need to get the Yukon back up and running asap...have any specific thoughts on where to look (big salvage yards, etc.)?
Thanks! I have Eibach 2" drop springs in the rear and just cranked down the torsions in the front--these springs ride great, just a little firmer than stock. I want the rear down another inch or so and just picked up a set of the Eibach 3" drop springs...guess I'll toss those in with the new center section. Hopefully the ride won't suffer any further.
