Thanks for posting the pictures of the Harland Sharp shaft rockers. Mike Becker worked with me to build a set of shaft rockers for a 348 drag motor that got way out of hand but has been fun. The engine is 369 ci with 409 heads, ross pistons from SHOW Cars, 3.250 stroke, 6.385 rods and a Howards roller cam. Alkydigger fixed me up with a Hilborn Injection. Pete Giroux makes a front cover to mount the fuel pump. Some time soon it will be completed and tested on a Dyno and I will be reporting the results when it happens. Hooley I must add that the Ross pistons were not right and neither Ross or the seller would help. DIAMOND PISTONS WORK GREAT. Dyno ed it at 520 HP . I am working on the rest of the car to race it in the 2020 season. GASSERS FOR EVER
