finally getting my gears done tomorrow..

[blazin]

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.
