Can a 8 inch handle 400 to 450 horsepower just asking don't know tha answer

it would be a good idea to upgrade your posi to higher spline. more splines more power it can handle. eaton makes some good shit

No you will brake it..spend the money once and be done with it.

8 inch rear ends can take a lot more abuse than people give them credit for. The only problem with them is, there's not lot of aftermarket support for them.

go to Jaws Gear and Axel, got my 8 inch done over there and they told me it could handle up to around 5xx something hp. im nowhere near that now but planning on the future

For a rearend that can handle almost anything you can throw at it the Ford 9" would be the way to go.

but for a budget rearend with a good supply of aftermarket, stock parts new and used. you cant beat the availability and prices of an 8.8 rearend.

thats the best option IMO

the difference in width from the stock 8" is minimal, i did mine about two years ago and from what I remember the difference was something around 3/8" total, which is nothing.

all I had to do was get rid of the fox mustang control arm brackets and weld on the spring perches (use the original 8" as a reference of the spacing of the brackets. setup your pinion angle and weld it up.

The fbody guys need a 9 inch aswell. but someone did a write up on using an 8.8 and just welding the spring perches onto it using mower axles and Lcas.
