total horsepower on my 360

285 to 300? hmmm maybe i shoudnt have skipped out on the kb pistons. i do belive the compression is 8:5. thanks guys im really thankful :) at least i dont let the chevy guys around get away with anything. the 65 nova box top thats around here i beat it everytime we run into each other. although i wonder if i'll have any trouble with the 71 ford mach 1.
