My friend bought a 66 Satellite racear. It ran decent. Decided to lash the valves. It had stamped steel rockers. So obviously a hydraulic cam. It also has a 6 pac balancer. Hew was told TRW /Speedpro type piston. Wiyh that balancer it has to have 6 pac rods as well. So it's all old school and heavy. Easily runs 11.40s and has dipped into the 11.30s. He runs it to about 6300. For the street I wouldn't worry about bob weight being heavy if you have the parts already.
