got a 05 SS silverado with a stroked 414 in it and a 150 wet shot of NOS. did the motor build about a year ago. Ran the truck hard with the NOS and every thing seamed fine. stopped to put gas and when restarted the truck had no oil pressure. by the third try she was tappin bad. let it sit for about half an hour and she started fine like nothing ever happened. I am wondering if I got air in the line? I have heard about a spring bypass if you create to much pressure in the line? not sure. any help or answers would help.
