Dana 60 S60 or Ford 9"
Just remember as racers we can break almost anything. I had a 1991 Dodge Daytona (2500 pounds) that I bought and put 100’s maybe a 1000 8 second passes. Those 4.30 gears were used when I bought the car and he was running 8.20’s with an Indy stroker. At that time I was only running 8.60’s@155mph. 1.21 best sixty foot time. Well I lit my two stage lights and when I broke the My Ford 9 inch I looked up and both stage lights were still on. Lol. Man I cleaned those teeth off clean. I should mention that car had 16-32 slicks on it
