We used a lot of the SPS rod bolts back in the 70,s/80,s and sold/ packaged by Mr Gasket as noted by Dave. I had a 283+060 (292 ) with 11/32 bolts which we regularly buzzed 9,500 rpm with a Manley type piston back in the day, Never had a failure and they always torque instantly to spec. I still have a set in a BJ 350 Z set of rods. Excellent bolt IMO.
