this is my first post on this site, so forgove me if its not up to par. i am in the midst of building my 92 toyota pickup, i am almost done my sas and 5" suspention lift, next summer i plan on swapping in a 4.3L vortec chevy from a 1996 blazer and i would like to run 36's or 37's but i wont be getting the tires till after the swap i have 31's now with the 3.0L engine, i was wondering what gears would be reccomended for the bigger tires, i know that with the stock engine 5.29's are highly suggested but if im putting the 4.3 in it will have a bunch more power than the stock engine so would i beable to put in 4.88's and still be practical to run on and off road?

thanks

yes then you have to factor in how much percentage lower transfer case gears add
i think the 4.7 adds 22% ? if thats right that jumps the rpm to 3935
