compression test

345man that table is pretty close. For example my 340 in my Valiant is 14:1 and when I did a compression test the cylinders were between 270-280psi which is right in line with the table. I also compared it to some of my old info from when I raced Buicks and those motors were 10.5:1 with 180psi which also matches the table. I know that cam shaft opening and closing rates effect cylinder pressure but this table is close enough.
