building a mild Daily driver 318

On the rear end, spend a few bucks on 90w and pop the cover off.
On my first duster the 7.25 never broke, I had a ex wife that was hard on motors, constantly blowing clutches.
I put 4 basically stock 318 with 4bbl, headers, duels and she broke them all.
I got the car back in the divorce, put one engine in it and ran it hard, 7.25 stayed together until I sold it.
Total years of abuse on the lowly 7.25 10 years behind a 4-speed.

I did build a 8.75 for the current duster I have.
$200 for a stock A body housing bare.
I had a 3.23 Sure grip but today's prices they run around $450.
Bought Dr. Diffs axles for $330.
The nice thing with Dr. Diffs axles is they will work with the brakes off your 7.25.
So....... I have about $550 out of pocket money in a 8.75
