Totally happy with my 434 and the service. Skip walked me thru my order and convinced me to go with the smaller hp package for my application. I've told me if I wanted to go with the larger package and wasn't happy with it's street manners then for 30 days I could return the cam, rockers, and intake for the ones I really needed. How could I go wrong with a offer like that. these are definitely the people you want to deal with and a great crew. Thanks
