i also have a petronix in my 55 with 374 pistons and a custom cam grind and valve springs. My dad and I could only get it to run really nicely at about 9-10 when the book was trying to say 6. i finally did get it to 6 and would idle, but it isn't very happy. i plan to go back to 9-10 and start from there when i am finally able to drive the thing.
