Default 9" chunk question

I know that there have been horror stories associated with using a "stock" third members in Fbody Moser units, but if i were to find a chunk with a daytona pinion support would that make it strong enough? The reason i ask is because i have been plagued with the whole $1500 center section offered by Moser. I just cant see spending that much, especially since NASCAR has been using simple daytona pinion support chunks for a long long time. Those "used" units are the ones that are appealing to me. They're cheap (like $450), they sometimes have detroits, and 31 spline with about any gears you can imagine. If they were set up or inspected professionally after purchase would they be adequate in a 450rwhp car? Im not talking about a regular stock case, but rather one with a daytona pinion support.

$2500 bucks is an awful lot to spend on a rear end especially if i dont plan on going to the track a lot. Scott has the budget chunk with the motorsport case, and if everyone agrees that the other daytona units are still weak then i guess i'll consider his set up.

So the question: Are 9" cases with a daytona pinion support definately strong enough to take the abuse?

A stock case will handle high 10's with a spool before you push out the caps. I have a few cars locally that still run a stock case and they have been running for over 6 years without any issues. What amount of power do you plan on puting down?

No more than 450 rwhp...for now. Maybe 550 with spray some time from now. Whats the total to my door cost of your kit with all ABS options and YOUR budget chunk?

Kurt,


I run the EXACT chunk you speak of. Mine is a pull out Winston cup center section. It is a 4.22gear(micropolished, etc), Detroit locker, and daytona pinion support, and 31 spline moser axles.

Right now, my car makes 460/430 on motor, i launch around 5000 off the 2-step on 26x10x15 Hoosier D05's.


I have NEVER had a problem with my setup, and feel extremly confident i will never have a problem with it either. I plan to spray a 150 shot via Nitro Dave's wet plate kit the next year. the rear end is the last of my worries, it's the motor/trans that worries me.

Our economy center section set up with any ratio, 31 spline truetrac, new bearings, 1330 yoke, solid pinion spacer is $975.00. A Moser housing and axle package set up for your stock ABS rings is $1085.00. So for $2060.00 you can have a Ford 9 inch shipped to you in 4 boxes to your door.

Let it be known that Scott is the man. If i can fit it into my budget i'll hollar at you. If i end up going with some other chunk then i'll still call you, cuz i still need the housing and axles!
I think that even though we're talkin $1700 to $2000 its still cheaper and smarter than rebuilding the stock pipe bomb. And besides, im almost positive that i can get most of my money back if i decide to sell it later.
