    Sounds plenty strong to me. It isn't much difference from stock.

    They are big and add more weight but not enough to hurt anything. if/when you get large tires is when the transmission might have problems but there are plenty of people with your setup but larger tires and don't have any problems.

    You will be fine with a 700r4/241. I was running that in mine with 1 ton axles with 4:56 gears and 35's. I am planning to leave the 700r4/241 in Donna's 90 K5 when I swap in the 1 tons with 4:56's and 36" swampers.

    If I'll go with 3.73 , will it be less hard to the trany or not?

    It will be harder for the trans and engine since you are running a lower gear ratio. Just make sure your tranny has a nice external oil cooler and you will be fine.

    I would go with the 4:10's. I have 3:73's in Donna's 90 with 31" tires and that is just about a perfect all around combo in my oponion so the 4:10's should net the same results with 33's. One thing to help the trans last is to keep it out of overdrive unless you are cruising about 55 mph or above. Also if you do alot of in town driving the 4:10's will work better because your engine will not lug as much as it would with 3:73's and 33's. On my 89 it was stock with 3:42's and 31" tires and when I went to 4:56's and 35's I was actually getting better gas milage because of how much in town driving I do. The truck just didn't seem to work as hard going from light to light and being stuck in traffic.
