    I have added a Gen V w/LIM to my bonnie, other mods are SD headers, 180 Stat, FWI. I will be getting a new tune. I will be adding higher ratio rockers at some point. My question is what size pulley to use NOW with current mods. 3.6 - 3.5 - 3.4.

    3.6 would be best.

    3.6". Drop pulleys once you have rockers.

    rockers help but are not needed to run the 3.6. you can add them later on, wont need the tune changed for the rockers.

    You don't need to tune for the rockers, but won't benefit from them unless you do tune for them. In car tune... Boxed tunes, eehhh, no difference.

    3.6", 3.2" pulley size doesn't matter. You might get more power out of a 3.8" tuned than 3.6" untuned... Lol

    i had rockers as a first mod, no headers or nothing. no tune either, all they did was clear up 5ยบ kr. what they do is flow better, no need to tune for them.
