Cranking compression

Ok,WHERE do I begin???? 1st,YES to all your question EXCEPT it is NOT a "race car" but a street/strip car.
When we put the motor together,we checked and re-checked everything and yes,it came out to 12:1 compression. The cam is ground on 108 but installed at 104 AND degreed in!!!!!!
My gauge is old and it may be off so Im gonna recheck today.
