I am building a 383 with a cam that has a .548 lift. dont have heads yet but I am going to buy some heads that flow around 280 cfm intake w/ 2.02/1.6 valves. going to have a low 60'scc. I am going witht he hsr intake and I am looking for someone to make a computer chip. There is a company called motorvation that does them through summit and then here is TPIS but their chips are like $500. Does anyone have any suggestions on who is the best out there for the right price?
