droopy89 Posted April 28, 2009 Report Share Posted April 28, 2009 That should have the 7.5 rearend,, honestly, dont waste your time beefin up that rearend,, for fairly cheap, id look for maybe a 8.5 rearend out of a 2nd gen, 5 speed S10, u can make those pretty tough Quote 1997 S10 EC Whats in it 106.9 Sq.ft.

Hypnotik DesignZ Posted April 28, 2009 Author Report Share Posted April 28, 2009 I have another rear end for it, I picked it out of a newer style blazer and it looks a little beefier would this be the 8.5 Quote Jensen 9511TS~For Sale JL Audio 300/4~For Sale JL Audio1000/1~For Sale Mephis 6.5 componet sets front and rear 4 15" Fi Q's in a 16 cuft box tuned to 29hrz Link to comment Share on other sites More sharing options...
pokertramp Posted April 28, 2009 Report Share Posted April 28, 2009 You would have to look at the cover and that would tell you what size it is. 7.5 rears are junk. I have one in my 82 regal and I could get a 7.5 posi with 3.73 gears for $300 but they are not worth it. I am saving up for a grand national 8.5 rear which run for $900 usually.. Your best bet is if that other one you have is a 8.5, use it. If not, look for one but most will run for $800 or more from what I have seen unless the person doesn't know what they have. Your other option is to get a custom built rear for $1,200...... Quote Link to comment Share on other sites More sharing options...

sully Posted April 28, 2009 Report Share Posted April 28, 2009 Looks like you drag race that blazer, i had an 89 with the 350cid conversion and the 700r4 tranny. the stock rear end had 273 gears and it sucked! i tried changing it to 373's and it still sucked. broke the ring gear when i hit the nitrous so i traded it out for a 12 bolt rear end with hardened axles and it never gave me any more issues. They have after market rear ends available thru Jeggs or Summitt Racing that are bullet proof if you are running slicks on it and pushing it hard you might want to try giving them a call to see what they have for you.

Hypnotik DesignZ Posted April 28, 2009 Author Report Share Posted April 28, 2009 It is the 8.5 i know this won't handle the horspower but what upgrades would help?

Moore941 Posted April 28, 2009 Report Share Posted April 28, 2009 (edited) It is the 8.5 i know this won't handle the horspower but what upgrades would help? What kind of power are u putting to the ground? edit: nvm i fail i see it now, umm honestly with 425 hp if ur runnin anything but street tires i would even waste ur time with the 8.5 i mean u could put some hardend gears in it with some hardened axles and have a cheaper fix but it will break i promise that, my firebird had an 8.5 in it and we put axles and gears in it then welded the rearend and i went through about six different passenger side axles in about a years time, if i were you and u wanted to beef it up i would sell that rear end then save up and put a Ford 9" under it with some 33 spline axles those are good for about 600 h.p. but i mean if u wanna save some money for the time being then go the other route and save for the 9" Edited April 28, 2009 by Moore941 Quote 2000 White Dodge Durango 5.9L Flowmaster 40 Series through 2 1/2" with and open cat. 1 Dc lvl5 18 4 6.5 seleniums and 2 D200 Selenium Horns on Rockford 500.2 Big three upgrade and a kinetik HC1800 in the back with all 1/0g knu wire shootin for 145+ Link to comment Share on other sites More sharing options...
