I have a 63 comet s-22 hardtop with a 351w(around 300 horse,320-350 lb-ft tq.) top loader 4-speed. stock 5-lug 8" rear with 3:50 gears, 4-wheel disc brakes from ssbc. I plan on mini tubbing the rear to hopefully fit at least 275/40/17's on 10.5 mustang bullit rims. -----Does this rearend even stand a chance on the street for a while? How about with a posi or mini spool? I have not come across a full spool for an 8" rear, is one available and if so will the 8" rear live with it? I eventually will install a stronger 9" or 8.8" rear when funds allow.


Any info will be very helpfull!!!!!

thanks

Here's what I can tell you from my info. The Ford 8" is capable of handling up to 400HP. Your 351 should not be overkill to the rearend. Also as long as you are not hammering this or as it may appear in your question you put slicks on the rear and hammer it then one may be seeing some early retirement on the 8". I would also check to see what the toploader is capable of. Since most t5's (stock) are at their match at 300Hp/330Lbs tq. I also believe that a stock drive shaft will handle up to 400HP. Their are many componenets overlooked when the engine is beefed up and other parts come apart. Hope this helps.

this info answers some of my concerns, thanks. the tires will be street tires. I'll stay away from nitto drag radials or slicks until i get a stronger rear. The tranny is a close ratio toploader from a '73 torino,(pretty sure). Eventually will be tremek tko 600. I still have to get a drive shaft made because car had no drivetrain in it when i bought it.

The shock from it being a stick will be hell on the driveline. Make sure that your pinion angle is correct.

If you shift it correctly and not hammer the rear, it'll be fine. 8" will support mid 11 second strip cars, so a street car with a mild 351W and a stick should not be a problem. HOWEVER - that is assuming the the rear end is set up spot on. Assembly errors will hurt it.

thanks, the reply's were very helpfull. I'll stick with the 8" for now. It will save a good chunk of $.
