I have Wilwoods on my '71. I used drum brake spindles since you had to butcher the disk brake spindle and I wanted to keep the OEMs. I went with what they then called "medium duty" which is a narrow vented rotor. The light duty are solid rotors and would probably be fine for drag racing. They work great, good price, good fit, no complaints. My car minimum weight was 3640.
