It all depends on what your compression is. Along with other things.

13:1

[wantinga400ex]

probably run like poo

[Steve1988]

would it damage the engine at all

At 13:1 on 87 pump gas it will be detonating like crap. That will hurt the engine if you go long enough. You should be running at least 96-97 octane in that thing..

yeah well the guy im buying it from says it will work fine on 93 but ill use octane booster or somethin i cant afford racing gas every week
