Matt I haven't seen 93 Octane in N. Ca. for a long time. I use 91 in my HP Mopars and have had no problem with performance. Sure I would like to have better like the old days. I have built two 426 wedge using Chryslers specs. They say you can get good performance using lower compression than keeping the old 10 to 1 & 10.5 to one engines and having to retard the timing back to the point they don't knock. One 426 with a single 4 bbl. and a .484". lift cam was lowered to 9.5 to 1 and it runs great on 91 octane and 34 degrees total advance. The other engine has 9.3 to 1 with 2x 4bbls also runs great with 36 degrees total advance. I use the adjustable vacuum advance canisters. I think this really helps. My son used to run his Charger at the drags and we tried the Octane booster and could hardly tell the difference and really adds to the cost of fuel. Bring Back The 110 we had in the 50's & 60's.
