Saw your truck today. Looked good what drop do u have.

Do you have that picture in your avatar a little bit bigger i want that sticker as my background looks bad ass

My truck is a 5 speed manual transmission, and I'm in the process of finding out my stock gear ratio... U think I'd have to change gears lower than 3:73's (if I had them stock or bought em) with a manual tranny? I'm also wanting to go to a T-56 later on down the road so maybe 4:10's wont be so bad at that point.

Maybe I'm thinking of a different one... I'm thinking somewhere around 222-226

I didnt even think about the tag in the glove box, and I worked in GM parts for years..lol I've asked the dealer to tell me my gears by VIN but they claim they can't, but when I was in parts I could figure it out... It took time, but I could get it done... I guess I could do the ol' tire revolution vs driveshaft revolutions but I'm getting lazy in my old age...lol Thanks for the info

P.S. I was wondering if I should get that cam that was posted for 300$ in the Parts for sale thread... I saw you commented on it. Do you think I could run it (tuned of course) w/out a turbo until I get one? If so, Would I gain or lose any noticable power?

Sorry havnt been on here alot lately but youre welcome. Yea the internals arent forged but with some ARP rod bolts, LS9 head gaskets, and ARP head studs these motors will hold alot.

Thanks for the info. It has been very helpful.

You speaking of that guy that's running 16 psi got me thinking... What kind of internal are in the 4.8? hypereutectic? I'm sure they're too cheap to used forged from the factory these days.

His user name is Quick. Hes the one that ran 16+psi in a 4.8 and hes the one to talk to about the T56 in a truck.

Yup cant wait myself. Right now i got 3.23 but i just got my locker today and now i can put my 4.10 in. You can search this site for the production codes in the glovebox n that should tell all.
