Mix your 93 pump gas with some 110 and go enjoy your car on the street...my goodness a 11 to 3 compression motor is nothing like these 14/15/16 to 1 compression beast out here racing on the strip...

the type of fuel at this level is very debateable..I HAVE PERSONALLY RUN 93 OCTANE AT 11 TO 1 and hurt nothing.......

i will almost guarantee you that at 11 to 3 compression this will make you a hot little street motor...just mix the gas to be safe on any detonation..

your orginal question was " is 11 to 3 compression too much for street"

now if ya building something to drive to work everyday then NO..but for a weekend warrior car..GO for it...

i will bet the 632 would have never made the HP you posted if the compression was 9/10 to 1...
...and like Bill said unless you know the exact cc's of the heads, deck height, thickness of head gasket etc... you will not know what the compression is..just beacuse the pistons say its a 11 to3 compression pistons doesn't make it that compression unless all the above are working hand in hand.....
