Thanks guys. The SCTA classes are 750cc A-VG and 1350 cc A-VF. The 750 (1955 Triumph) has no front brake, drum rear. Ran 120.9 at Bonneville.. so far. The 1350 is a dual-engine 1955 Triumph, no front brake, disc rear. Ran 129 mph so far, only have 12 or so runs on it as of yet, should be able to up that a decent amount.
