Looks just like my order from BTR less the cam. What lifters are you running. I'm debating pulling my heads and swapping lifters. I debated swapping LS7 lifters as a few people had problems with them so curious what u running.

Bump

what is your factory gear ratio?

 

[Chrismnj]

AXLE,REAR,3.08 RATIO 3.08R(GU4)

 

[12BlackTahoe]

I would go with 4.10

Edit

you have 32" tires correct? do you really care about gas mileage?

 

[Chrismnj]

yes 32" tire, I mean what are we talking about as far as gas mileage? 1 gal to a mile?

 

[12BlackTahoe]

4.10 as being better if you are doing a lot of serious hauling and towing in hills, etc. Sounds like the 3.73 will be more than adequate for your needs. People who have the 4:10 gear swear there is a huge difference in power.

3.08's suck performance wise.

 

[12BlackTahoe]

better off calling a shop that specializes in that. If it was me I would go with 4.10 just my 2 cents

 

[Chrismnj]

to my understanding I need to do front and rear?
