Ps-91= BIG $$$.....We have almost the exact same upgrades, however I have headers. I am in the process of upgrading my ignition system as well and I think I am going with the Crane ps-41 coil. It pumps out 40,000 which is enough for my needs. I am also going to get the XR 3000 ignition system...jc whitney sells it for around 115.00. If you get the PS-91 let me know the gains, if its worth it I might get one as well.
Good Luck-Travis 77z
