I have been dealing with Joe Sherman in CA for 20 years, I live on the East coast and when I first started drag racing I came across alot of articals in various mags that detailed his engine/car builds and his combinations always made big HP. I decided to call him one day and HE answered and patiently helped me with all my questions about a 383 SBC I was building. He sold me a cam and my engine ran some great #s. Through the years I bought some ported heads, a shortblock and more cams but never a complete engine. Every single time I have called his shop HE still answers the phone and he still takes the time to talk HP. Joe Sherman is a VERY educated engine builder and his combos always run great. I wouldn't hesitate one sec to buy an engine from this guy!!
