They used to be called Clifford Research. They made a lot of Ford six performance stuff back in the 70's. Probably called c.performance now.
I honestly dont know if they get 350hp or not but that is my goal. I know its extremely easy to get 255hp with a few turns of the screws on the injection pump so I bet 350 is attainable with a little modding.I think I already have the turbo for it and I know the local injection shop here can handle the pump and injectors. I havent heard of clifford research I will check it out. I have heard of clifford performance the people that deal with 6 cylinder power.
