Opinion On Hughes Engines
I have a Hughes solid flat tappet cam in my engine, never had a problem. I've dealt with Dave and he was very polite.
I can sometimes understand when someones main focus is such that when questions arise from an unknowing point of view people tend to think that you are arrogant. It's really not the case. Dave is a very knowledgable and highly skilled craftsman. Just because he doesn't have the demeanor to deal with people that may not have the same knowledge as him doesn't make him a bad person. Nor does it mean his work or products aren't top rate. He's just focused.
As 416stroker said once you are on the same page with him all is well.
BTW his cam picked up .4 in my car over the Mopar .590 cam. That is substantial.
