ok guys I installed the ls1 into the 4.8's place, everything was used and an ls6 cam was installed. The starter will not crank with the key but using a screwdriver it will fire up and die... i have started it several times and have not seen the oil pressure rise yet and sounds very noisy, is this where the lifters and such have not pumped up yet? Would security be an issue with the starting, the security light in the truck is on at all times. I have never owned one of these trucks nor seen this one before the install so is this normal??

There was also a cadillac dash installed, would this be causing any trouble?

Any and all help is greatly appreciated

Thanks alot
Jarrod
