Brickman,

I agree with Richard. Octane booster isn't worth the money. There are magazine articles all over the place that tell you how to get mega-HP on 93 octane gas. It just takes cubic inches and the right combination of parts.

I built a killer 454 with a little over 9:1 compression, Comp Cams 305H Magnum cam, stock oval port closed chamber heads, hyper-eutectic pistons, Holley 780 DP, dual plane manifold, Mallory Unilite, long-tube headers and a good balance job. Hooked it to a toploader in an A-bone sedan, and it would flat move. Low 12's on street tires with closed exhaust.

It's in the parts, man . . . it's in the parts.
