Give me the ups and downs of a 6" lift for a daily driver

But the lower first gear would be better with the 700R4. I would switch hubs to manual, get a part time conversion. Better on the front axle, less drag, and you dont want to back up and not have 4 wheel drive. If your axles have 3.73's yer fine if they are 3.08 then you'll definately want to swap in 4.56's. I ran a 86 K5 with 305/700R4/NP208 with 4.56 gears and a locker. You can go 4" lft with the 35's. Probly find a better spring rate and better ride. I only had to do very minor fender trimming, and since you dont plan to flex it out much should be fine. If possible stay away from blocks in back. With a 383 and a 4" spring lift I would get nasty wheel hop in back. Not good!!

I'd probably leave the 3.73's in along with the TH350, lift it 4" and stick 35's on it. If you swap out the trans for a 700, you should change ratios, especially when beach running. I took mine to Big Shell on North Padre and it did well with the 4.10's, but coulda asked for a little more gear. I have blocks on the back of mine, actually, I have blocks from a 6" kit because my stock springs were sagging. I had/have no problems with wheel hop, and mine is wayyyyyy heavier than yours.

4" will fit 35's, and since you aren't flexing the truck on rocks, it should be just fine. Just go with 6" if you want to be a little taller, but your front D-shaft may need some work. My 4" was actually a 5" when measured, the shaft was too short. Bought the Superlift d-shaft spacer and all was well.

The 4" will save you some headaches and you will get a better ride out of some kits than stock. Tuff Country will be the softest. The Tuff Country HD has the closest spring rate to stock. Skyjacker is about 2x above that for the spring rate, but I like it. Not too rough, not too soft.

To do it right? Order the kit, get the braided stainless brake lines for it and the raised steering arm. You get that, you will have everything you need.

I drive my Burb about 4 days a week around town. 5" lift with 35's. It does affect your braking, but it's not a big deal.

I wouldn't put a 700R4 behind a BBC with possibly wanting to run 35's and not knowing the gears in the axles. You wouldn't be able to use the OD if you have 3.08 gears, and the possibilities of burning it up are just to great.

When I pulled the motor in my '90 Burb (w/3.42's, 35's and a 700R4) the trans fluid looked very dark. I never put it in OD, and still burnt the fluid....

The stock 700r4 will get its ass kicked by those tires and motor. With the bb you should have the tq to push it in od but i wouldn't recomend a bb, stock 700r4, and 35's for a rig that will be in the sand. I run a 6" superlift with 35x12.50's and it did JUST FINE off road but I hardly saw OD when i had the stock 350 in there. If you want it to accelerate as hard as it did with smaller tires you'll want to regear to 4.56 or 4.10's. With OD rpm's shouldn't be a problem. Road manners aren't bad at all...I regularly made the trip to the lake for work on some VERY windy roads and could keep up with all the little trucks and cars without feeling like it was gonna roll down the canyon...even did it with no powersteering 3 days in a row...didn't need to lift weights after that drive LOL

The t-case(if its a 208) should have an aluminum skin and a burly chain for its guts.

The th350 isn't any stronger than the 700r4 and it doesn't have OD.

a built 700 with the corvette stuff and a nice filter and cooler should do the trick.
