No telling. It depends on too many things besides the "static" CR, not the least of which is the cam. The less cam you have, the higher the gauge indication will be; and its timing (valve timing, not ignition timing) affects it too.
Those numbers are pretty typical for a stock motor in the 8½:1 range, with a "peanut" cam or a 929 cam or similar.

im just wondering cause the car has nice power in the first few gears..once it starts revving high in 3 & 4th it feels like its not pulling hard i was thinking it maybe was lower than usual comp. ratio cause i have 73cc heads. but i was hoping the tall pistons woud make up for it..i ported them myself and it helped a little.
i was thinking it could be the gear ratio..its a 9-bolt, all i found when i pulled off the cover was these #s which i have no idea what they mean..
