That cam will want 9.5:1 to 10.75:1 static compression ratio with 10.00 to 10.25 as ideal. Unless you have changed pistons in the motor, it's probably down in the 8's somewhere. Too much cam with too little static compression ratio will make a weak motor. It'll take pistons with a pop-up (dome) to make more compression. Do you have any idea what pistons are in the motor?
