12 bolt posi

how wide is a rear diff housing on a F body car and does anyone know of any 12 bolts that just slide under thats the right length or a tiny bit shorter doesn't matter waht bracets are would be nice if their were the same. and also how hard is it to put a 4 link rear end in or if its worth it im only goign to be making about 370 to 425 hp when its done and want to be run around low 11s to mid 12s in a 1/4 mile with out going super cheep what can i get a way with im in no rush to do it but i just wanna do it right with out way over doing i don't want to have to change my rear end every couple of years

thanks

leave john alone hes a cool guy, and someone please answer my question

i got a 12-bolt from moser engineering. its pretty much a direct bolt up, stock fit. the company is great to work with and they send the thing pre-assembled and read to install. there are a couple things you gotta do to make everything match up, but all in all its a great set up...

how much all that cost u if u remember off hand also was wondering if anyone knows if a 8.8" rearend can fit in an 85 F body from a mustang

Chevyracin I'm sure your 3.4 really needed a 12 bolt...

you can make anything fit. i know that the ford 9" is popular. i went with 12 bolt cause it was easiest to put in (was my train of thinking atleast)

all together i paid over 3 grand for the entire project. the rear-end itself was 2.5K and then another couple hundred for a driveshaft. my case was abnormal though cause i had to do extra stuff to get it to fit cause of the rear-end i got. the one you would get might be cheapier than that...

k thanks becuase i want an ok rearend that will last a while cuz my brother said if a 8.8" inch can go in with out doing any major work that he could get one made up for a couple hundred bucks and i would be happy with that and i do not go way over board and spend way more then i should off

yeah, you can get the moser for about a grand but it wont be as bad ass. mine is a circle track axle that can handle over 750 hp, as is, but i had to pay for it...

yah see i only wanna make about 375 to 425 horse power this is my first car i don't plan to go WAY over board cuz i plan to sell it in like 6 years

i know you can get 12-bolts from other companies, i just havent looked into it. i think you should go with that 8.8 if it will work...

yah thats what i thought too ill have to search all this out on the net i was just wondering if anyone has done it or seen it done befor befor i buy all this stuff that doesn't even work or if does works crappy
my brother 8.8" would be the best it would be cheep and work awesome thanks for all the help

hate to be a downer, but chances of you running 11's are pretty slim with 375 to 425hp. But even so, i think the cost of a 12 bolt for that power level, and the fact that you plan on selling it down the road, makes it not worth it. Also not to be a dick, but on average, youre going to make less power than you aim for, so im quite sure that if you proporly set up your ten bolt rear youll be just fine.

Chevyracin I'm sure your 3.4 really needed a 12 bolt...

no it definitely didnt, at least not now. i do have plans for the car when i get out of college. call it, planning ahead. plus its just pimp to say i have a 12 bolt.

goin FI?

havent quite decided if im gonna keep it v-6 or go up to eight. either way im sure FI will be involved.
