I sent them my mechanical secondary carbs. I had them rebuilt, choke horn milled, high flow fuel lines installed, bench tested with their metering block and a few other "tricks" done. They did a great job, were informative and very helpful in selecting the modifications my motor would benefit from. Ask Ben for specific tuning help for your application.
My 493" hydraulicly cammed motor need some jetting changes on the dyno, but once done it pulled 680+ horsepower at 5500 RPM. Not too bad for a 40 plus year old design.

second to none tuning when you give them your correct info. Buddy has their carbs on his original "pain in the balls" six pack 71 RR. He's never looked back.
