What is the standard on the most compression

Well I am not one for the heat an the old barracuda will be without a/c. Aluminum headed aluminum block 426 hemi with two F1 throttle bodies and the motor will be in the 500 inch size. I have just decided to use the 12.5 to 1 pistons I have and run some 116 with my 93.....

And Kim you are wrong.. It was my Aunt. :)
