I got this wesite for you to check out. SMI CarburetorSMI- Sean Murphy Induction

It runs really good! I usually run 93 octane but had a tank of 89 at one point and it stayed running good and detonation free lol but my ? Is that I have an automatic and I plan on getting a looser converter just to help my cause but would a 4150 HP be ok for an automatic? I assume it's that way to go bc it's a light jeep with 3.73 gears and I like the idea of air bleed adjustments
