so ive been building up my 347. got the bottom end from frpp preassembled. just got the motor in and all set up ready to crank over. been having timing issues and such. today i do a compression test and NOTHING. 0 compression. what could this be? my book said to crank the rockers to 10ft/lbs...but thats factory ones, i have pro magnums from comp cams. im thinkin it might be too much and its holding the valves open. anyone got some advice for me? snow has already started flying down here so i wanna get her running so i can bring her home to my garage
