I would be just as worried about the 50 yr old 2.75" diameter thin wall Chevy II driveshaft. For peace of mind, I put a Denny's HD shaft in my '65 Chevy II stick car. Dennys uses the Spicer joints, and they claim a 500 hp rating for this shaft with stock-size 1310 joints. It's a nice piece. A little pricey, but nice. I'm sure I'll blow up the Muncie or the 8.2" 10-bolt before I hurt the shaft.
