i swapped a 6.0 into my 1500. and i got a comp cam and put that into it with comp valve springs also. and put a summit double roller timing chain set on it. and when i got it into the truck and started it. it makes a aweful noise when it starts just sounds loud. and then it says no oil pressure. i only had it running 5 to 10 seconds at most. just wondering what i should do to check if somethings wrong or if oil just hasent got thru the engine yet. let me know what you guys think!!!! THANKS
