pump gas build

yeah I get that... but he never said anything to that point about a performance boost, only that he wanted an engine to run on pump gas...... after reading so much here and on teh other site, and working thru my own engine, I know there's alot that can be done...... prior to the current project Id rebuilt a couple of /6s over the years.... both back to stock, with only necessary machine work, to bring tolerances back where they need to be.
Lol! Well, true as that is, We're gearhead guilty & "pump-gas build" usually means the most output in the desired RPM range on pump PREMIUM. Big difference in possibilities 87 to 93/94 .......not that it's relevant, but a modern Hyundai 2.5L is making 190+ hp na and running just over 13:1 squeeze on 87 regular.......
