8.8 Rearend Strength???

i have a 67 mustang coupe i am building a stoker 302 for it dual quads and high flow heads i was wondering how much horsepower can a stock 8.8 take? i might add nitrous soo i need to know if it will handle it i plan on using a kit... a kit that makes it a limited slip by changing the pumpkin... but it will still be a 28 spline.. does anyone recomend using a 32 spline? for strength i dont know how much power i will be pushing can someone estimate for me with what i have told u?

Stock 67 rear ends are 8", not 8.8 - unless you've swapped in a late model unit. They are good up to about 350 HP or so, depending. Clutch type differentials last about 10 minutes when drag racing. For a nitrous unit, a 9" with 31 spline would be recommended. That's only one less than a 32, but it's still good. From the info in the post, I'd say it won't hardly idle let alone make any power. You'll have to post more info.

well here is my full plann on the buld bored out 30 over stroker kit new rings high compression pistons (maybe 9:1 not shure what pictons yet) edelbrock preformer rpm heads preformer rpm dual plane intake eagle rotating assembly (crank) rpiston rings new rods (in the stroker kit) comp cams cam not shure what lobes yet (ny recomendations) rolled rockers roller lifters milodon dry sump panand hooker headers that should be a complete moter let me know if i missed any parts... and msd 6al module and distributor how much power u think? im thinkin somewhere in the ball park of 350-400 ... ok and ya it must have a 8 inch sorry but i know a guy and i can get a good price on a disk brake 9 inch currie soo i might get that but im on a budget of almost nothing... but im trying and im putting tubular suspention coilovers and all that jaz and flaming river rack and pinion soo there is my build for the enxt year... i would appreciate some feedback =]

You'll need to increase your budget up some from the "almost nothing" level to get that done. You're talking nearly $3500+ in suspension mods only. Lesse - a 30 over stroker at 9:1 with a dry sump. My first recommendation would be to step away from the magazines for a while. Review some of the 331 and 347 builds here and maybe engage those folks about what's up. 350 is reasonable, 9:1 is not really high compression. You plan to use all Edelbrock stuff, get their cam too. If you run the dual carb intake, you'll need the tight lobe separation to help the thing idle. The dual carb intakes are cool looking, but make consistently less power than a single 4 bbl intake.

im not reading out of a magazine never touched one i have a budget of about 10 grand do finish this build over the next year im building it out of my garage and i have hurd that edelbrock cams are ****... i have been thinking of running the dual quad because ive hurd they make power but in moderation ive also hurd without the right heads u will jus flood the puppy i was also thinking of maybe supercharging it... i have a supercharger for it but it would need a rebuild kit and evrything and then i would have to modify my hood but i would love to go that route or maybe buy a procharger or something make it a lil easyr and go efi imnot shure yet thats why im getting some tips on here

You need to figure out what you want first, what are your goals, what do you want to do with it.

Please forget about what you "hurd"........ Seems to me you been getting a little bit of misinformation, we'll help but you'll need to listen a little too !!

about the 8.8...does it weigh less than a 9 inch? if so, how much?

Yes its lighter and more efficient, but slightly weaker Stock vs Stock.

I'm going to guess about 30-40# lighter and thats 28 spline vs. 28 spline

yeah thank you i am jus trying to build an engine for my car that will pund the flipping pavment i want it to haul ass i wil post a pic of it soon it has a nice new paint job on it soo any info and suggestions on what parts/ engine combo i should use would be greatly appreciated

Thier are a bunch of nice Street / Strip builds already posted on here.

And 400-500 hp is pretty easy to do N/A with a 347" motor with good heads

I wouldnt waste my time with 2x4's, a single 4 will make make more power and be much simpler and less expensive.

You may even want to consider a Ford Racing Crate Motor.
