Yes, but no, that looks like the OEM Convertor from my first 74 Z28 that was destroyed in August of 80. They used 6 mounting points with 3/8 bolts and were rated at 2400 stall. A Z28 was the only Camaro equipped with a TH400 in 74 as they were considered special high perf. I have also seen the 6 lug convertor in 1 ton trucks, no idea on their specs.
