How muck more lift do you get by switching to 1.6 rockers. I already have a mild cam(have no specs its was already in the engine) headers, wieand intake, 600 edelbrock and msd street fire dist, turbo 400 and 373 posi. I just need alittle more power to get me by til I swap the big block in. not looking to spend a lot of money but my daughter got engaged and I have to pay for a wedding by september it kind slowed up the big block build til next year. thanks, Wes
