for me cost is not a issue,i buy the best parts.i only want to do it one time.i have gone to a bunch of builders so i have a feel for what is good.i met pete from best machine at norwalk in 2009 and had a good feeling.i talked to pete and chuck and got the pso motor started.they went out of their way to find a buyer for my old b1 motor so could build the new one .they held a set of heads for me.they put all the best parts in it ,the motor made sick power i am a customer for life.i drive 11 hours to get there,when you know you have a good shop you just know thanks again best machine
