Wondering how much torque/hp the stock g body th350 drive shafts can take.

My son broke his after the last owner raced the hell out of the car. My learning curve on it was to take the time to paint a 1/4 wide very straight white line between the ends. Periodically check it for straight. (visually)You should see it b4 it lets go.

A well known and trusted driveshaft maker nere me told me a stock gbody drivershaft is limited to around 350-375 horse at the wheels. That being said my buddies car dynoed at 360 to the wheels and after some hard launches at the track he found it was bent and slightly twisted.

Take some time and read up on driveshaft critical RPM - Precision Shaft Technologies has a nice chart
