Powerlog is going in this friday. Need to send my money to SmoothFlow friday as well. My overkill is programmed for a 3.5 but I'm thinking with my mods I should go with a 3.6 instead. I don't think the pcm will mind. Im not sure if the autolite 605's are going to hold up to a pulley yet but i will find out when i scan after. I'm thinking I should stick with a 3.6. In my head dropping to a 3.5 is a little much without some internal work like rockers. what do you guys think?
