i was going to see what the prices where. i was thinking of mixing 106, 110 or 116 with 93 to get around 100 octane.
i've got some nice indy aluminum heads and with the quench at 36 i didn't think i would need more than 100 octane to run the streets. i've also got both sides of the intake tapped for rear head cooling. as can be seen in my sig.
