I dont know if this gas is just something where I live, but it is an unleadded street legal fuel with 100 octane that you can pump directly into your street car, it costs around $4.00 a gallon. As far as the compression goes, you can run over 10:1 compression with iron heads on pump gas, but it usually doenst work very well unless you have some other stuff (cam/quench/...) right for it. Also, the reason that I recommended the 4000 stall is that the victor jr intake is not supposed to make good power until. 3500 RPM or higher especially on a smaller motor like your 327. I agree that if you changed your intake, a stall that large would not be needed.
