i live on East coast and Never heard of him..but i bet many people on the West Coast has heard of Gene Fulton and Par racing engines located on the East Coast...if this tell you anything..
not saying he ( Sherman) is not a great engine builder....i would definatley check his local references meaning people who have had engines built by him..i would speak with a minimum of 5 references,if you can't find them..then RUN !..a motor is the quickest way to get burned in this business...trust me on this one..
