i need a 9 inch rear for a 4th gen or considering 12 bolt but i dont know if that will hold my power with the 6spd

are you building that tranny up first?? I really think its only rated to 450 ft lbs give or take depending on the year/model...


But i agree your rears the worst part now. Remember that TA that blew the rear right as you were about to stage?? It kinda made me laugh cause I knew u had the same rear

A 12 bolt? It should hold your power, are you buying aftermarket or a stock 9 inch/12 bolt?


No problem man its nothing at all. My number is 724-812-6007..just keep me updated when you wanna go and all that good stuff.

Yea if i have time to grab you on the way i would, but it might be a race against time kinda thing. We'll see tho.


Anyone know of any good tall cliffs in greensburg.. Maybe with like, a firebird eating monster at the bottom. Maybe???


Imma make some calls and see if anyone wants this shell.

If I had a place to store it Id torch it piece by piece until it all fit in my bed lol, I just dont know of anywhere I could drop it off. A cliff might work tho..

Big cliff



arg. I don't know. If i can figure a way to swing it I'll let yall know. I wasn't really planning on buying a rear end this winter but hmmmm.


But i gotta be in Erie by 9AM tomorrow, So im off to bed. It's funny no one posts in this thread for like 3 weeks then theres like 12 posts tho..

i'm gonna buy a 9" possibly even tho i dont want FORD parts on my car. Just doesnt seem right but everyone with a T56 recommends it and with my power i think the 12 bolt has a chance to break if the trans dont break first

I'm not rebuilding it. I'm gonna run it til it blows. They are rated at 450lbft but it will hold more than that as long as i dont abuse it too much. And i wont

hotrod16105

Keep me posted on those units, thats whats in my bird.

I might be interested in some parts if you do pick it up.

LMSkyliner

iTrader: (1)

I am 99.9% sure there is an aftermarket chevy version of the 9 bolt available from summit. Same old 9 bolt in a convenient non ford package!


And thats fine and dandy, just don't blow it up too soon! I'd hate to see anyone waste a good T56

Orr89RocZ

iTrader: (20)

They have bolt in 9"'s for GM's but its still a ford rear. I wanted a 12 bolt but with a stick you can still break those. A 9" is hard to break

Stippy17

iTrader: (6)

If you break a 9" Ill kick your ***..period.

hotrod16105

Anything can happen. I wouldn't want that to happen, but if it did, i'd like to see that launch.

Stippy17

iTrader: (6)

Anything can happen, but you dont see even high HP cars breaking aftermarket 9" rears every day. What kind of warranty do those rears come with, any?

hotrod16105

I cant say i've seen one break. Not sure what kind of warranty, if any, they would come with. Suppose it would depend on who you buy it from.

Orr89RocZ

iTrader: (20)

seen 12 bolts break ring/pinions on a 11 second manual car. I hope to touch 9's

hotrod16105

Your rear should have broken already. I'd be curious to see how long it would hold. Whoever is behind you at the track might not appreciate it though.

Orr89RocZ

iTrader: (20)

If i was keeping the auto, i'd totally run this car with its rear end as it sits. I dont know anyone in the 9's with stock rear But i know any effort thru that manual with the clutch i'm gonna use, it will shred the ring gear or crack the carrier for sure.

ruberbanman126

If anyone needs a ford 9 inch i have like 3, 4 or 5 of them sitting down at my dads garage. One of them is even narrowed. I have no idea what gears they have or the condition of them, if anyone is interested i can get the specs for you.

LMSkyliner

iTrader: (1)

Justin, I was doing some research on rear-ends and heres basically what i found:

theres a 8.5" 10 bolt that is nearly as strong as 12 bolts

12 bolts can be very strong, and have less drivetrain loss than 9"s, and should work no problem for what your doing. They arn't the strongest option however, and they all seem to have pretty bad gear whine.

9" is the strongest, though there is alittle more drivetrain loss. Its about the same price and maybe even cheaper?? I havn't found anything on the gear whine but i would suspect its more to do with the gears, and would be in the 9"'s too.

S60's are actually stronger than 9"'s, but are heavier, and well.. yea. Not needed.


a guy on TGO recommended these guys in a post i was reading
http://www.quickperformance.com/index.htm

ruberbanman126

Anyone interested in these?, I'll give you a good deal.

Orr89RocZ

iTrader: (20)

they dont have the torque arm mount setup like stock rears for fbodys have. If i go 9" i'll need the 4thgen wide spec version anyway with torque arm mount on the housing

ruberbanman126

So what your saying is the rears that i have wont work with these cars even if they were modded?

Orr89RocZ

iTrader: (20)

they will need to either have a tq arm mount welded on and spring perches/LCA mounts as well, plus get either explorer disk brakes and adapt them to your stock stuff, or get custom brackets made up for our stock brakes

OR you will have to run a different type of suspension like a 4 link or something and still custom weld mounts for all that. I dont think its worth the effort

Lol besides. Cant have Ford parts in a chevy!!

I'm still trying to decide if I can build a 90-92 (28 spline) 10 bolt strong enough to handle what I need....

Orr89RocZ

iTrader: (20)

mines bone stock and held over 500whp in a auto. In a manual tho i'm not sure how long it last. for you being in the 350-400whp range eventually it may last enough as long as you dont try to kill it off the line. 87TA was doing 1.5-1.6's on his stocker and 450ish whp 406 and its holding great but he aint fully launching it

LMSkyliner

iTrader: (1)

yea I know, but I hate worrying. The 90-92 rear-ends are different than the 85-90 rears and should have the same max strength as any 4th gen rear but dont add the extra 2 inches. I was thinking of taking a 90-92 rear and just changing all the guts. stronger posi, 3.73 gears, axles, c-clip elims, and anything else i can figure out that would make it stronger... I was betting that it would hold the 400 ish RWHP and 500 ish RWTQ. I wouldnt spray till the 60 foot anyways so that shouldnt be as much of an issue (wanna get into second at LEAST before the juice kicks in).

/shrugs..

3.73s should be good behind a T56 though. I think I would stay 3.42s if i went with TKO600 though. That extra gear means alot to me on the highway.

Alright guys well Im saving up for Heads again, after I payed a little fine I had and bought the TH400 Tranny. But I might be spending a good bit again and setting back heads again lol. Reason is I found 3 Thirdgen Trans Ams about an hour and a half away from me that a guy is trying to get rid of. Says he doesnt have titles to any of the cars, but I figure Ill scoop them up for around $600 for all three and part them out to make my money back plus a good bit to go towards the build (Especially heads lol). I may keep the best looking one even tho it doesnt have a title, and keep it for a sole drag car but who knows we'll have to see.

Im still trying to negotiate with the guy. He wanted $750 for them, and I have him down to $650 right now. If he'll do $600 Ill take em.

Ill let you guys know if this is gonna happen, or if it just falls through.

I'll trade you, but only when yours is done. I won't even ask for any cash.

Quick question, i have a Ford 10.25inch with 4.10 gears and a locker/posi unit in it, and i have someone that wants to buy it but im not sure what a fair price is. I know this isnt a third gen related question but could anyone help me. I was thinking of selling it for around $800-$1000.

t/agta

i know its pretty early still, but im trying to setup a meet. When it warms up, im trying to have everybody come to the sonic at the pittsbugh mills. Now i'm hoping it will be mostly f-bodies, but everyone is invited. We're Trying to make this the biggest "unofficial" meet of the year. When it starts to warm up ill post the date. Just let me know whos interested. Thanks

LMSkyliner

iTrader: (1)

I'm in! But I'll need till probably mid June to get the car up to 100%.

However, I think we should meet somewhere with some fun roads nearby, so that we can all go cruise. Or maybe somewhere that we can terrorize some imports or mustangs .

Im just saying that if we have the choice, I think that I'd rather be wasting oil reserves than putzing around a parking lot for 3 hours. Maybe we could chill out and catch up on the winter progress, then go drive for an hour.

besides, Like 4 of us needa get some fresh-engine-break-in-miles

Im up for it, but my car wont be done until hopefully May sometime..

I have my 383 shortblock for sale 2500 bucks. all forged, 11 to 1 compression with 64cc head. cant beat it, 1600 miles its like new

LMSkyliner

iTrader: (1)

I'd keep your garage door locked until my engine is done

t/agta

my idea was we'd all meet there, hang out for an hour or so, then we can do it woodward style and all leave at once and just cruise 28 and get off at some point and terrorize some towns. Ya I'm not one for sitting around doing nothing for hours upon hours. lol

and btw the ricers and mustangs will be with us so its easy pickins'. lol

if my 400 is done and in the car i'm gonna break in the motor n/a and work on getting the tune on that done with the new ecm. will take about a week of good hard driving to break in the motor I hope to have it out but it will only be a 350ish whp car haha not for long tho

not sure of a timeline for this build, but it doesnt get decent out til april anyway so i probly wont have the car out until atleast then

t/agta

drivin my 6 speed 00 t/a in the snow is...... interesting. to say the least. lol

I'm getting jealous. My poor bird isn't getting anything done to it this winter.

LMSkyliner

iTrader: (1)

so do something to it

Im trying to think..

this spring we'll have 3 new engines and 2 new trannys bare minimum.. thats alot of change for a small community

hotrod16105

I would like to but my other project has taken the lead. Might get to tune it in the spring or something.

LMSkyliner

iTrader: (1)

other project????


hey justin.. just talkin with my dad we MAY honestly be interested in the entire shortblock, or even the shortblock + heads depending on how the price goes. yanno, if ya get no hits or interest or anything etc.

hotrod16105

I have a non-thirdgen project. Its a 1966 AMC Ambassador. Hope to have it done this spring/summer.

Orr89RocZ

iTrader: (20)

took the cam out. I am thinking of keeping my heads but things could change. Let me know what yall are thinking, i may give it all up for a good price, but mainly want to get rid of shortblock at this time. I like my heads

LMSkyliner

iTrader: (1)

well leme know when it gets to the "sell-it-now point". I dont think I can build my own for less than $2000 so my dad agreed to watch how your shortblock does. If it wasnt for those weaker 8740 rod bolts I'd be making an offer right now. Did you ever get a quote to see how much it would be to swap for 2000s?

and i dont have the money for shortblock+heads anyways so thats just a daydream lol. I'd havta try and sell all 3 of my engines to find that one. Though it may be worth it.

Orr89RocZ

iTrader: (20)

90 bucks for bolts, 25 to check rod housing bores to make sure they didnt change from the bolt upgrade. It wont need rebalanced either. ARP 2000's will be good to damn near 800-1000hp i think. L19's are even more so, but i feel the standards are good for 600-700 range at crank.

You can send rods to golen and they will do it.

I wouldnt worry about the ARP 8740's. I went 10's on that setup banging off the limiter at 6800 rpms alot IF they couldnt hold they would have broke by now. I feel they are good enough for your build.

I'm trying to get 2500, whats the next best offer you can give me? Its not a sell it now point yet, but the faster i sell it, the faster i can get the new motor in Faster the better for me Hit me up
