ive been planning on getting my diffs rebuilt for the last 2 weeks.. had the parts. but i have the top off the blazer and its been the raining. but i dropped it off today. putting a eaton posi in with 4.56 gears. it has 3.08's now. think i'll notice a difference? im running a 383 with 465hp/492tq, 700 r4 and a 205 transfercase and 35 inch tires. ive never been in a truck with 4.56 gears. will it be a hugh difference? the blazer is quick now. im pretty pumped to drive it.

night and day and your overdrive will come in handy for sure. report back what your rpm's @ 65 are when you get it back.

im still waiting on my speedo cable, should be in next week. i could do 70 km/h or more in second gear lol. so the 4.56's should work a little better with my setup. all i know is.. .it hauled ass with the 308s off the line. the 4.56 will most likley scare me at first lol.

I've got 4.56 gears in my 69 K20 with 35"s - your transmission will be a big plus with those gears compared to my SM465. You're going to notice a tremendous difference in power!!!

blazin · 06-02-2010, 06:56 PM

wow!!! its crazy fast off the line.. almost scary. well spent money

chevyblazer · 06-03-2010, 02:05 AM

i could smoke the tires off before i changed the gears from 308 to 456. but i spent to much money on the tires and the blazer to be trying to wreck it.
