I recently started my Texas Speed LS3 after priming it with an home DIY primer taped into the oil galley at the front of the block on the driver's side. Even after priming with Joe Gibbs BR oil it took longer than a 10 second cranking to build oil pressure up to 40psi when I primed with the starter (after my initial priming). I had a mechanical gauge tapped into the area above the oil filter. After priming it fired right up and had 60+psi at idle on my Racepak dash.
Pull the spark plugs and SPIN the BITCH UP! with the starter motor or build a primer and tap it into the front galley plug on the drivers side of the motor. Anyone recommending starting the motor when its exhibiting no oil pressure is a complete BUFFOON! Make darn sure you have oil pressure before powering up your motor.
Mine took forever to prime. I pulled the plugs, disconnected the coils and removed the fuel pump relay and spun it over for about 15-20 seconds at a time. Took 4-5 times of doing that before I got pressure.

Read the entire thread...it was not a fresh engine. It was ran before. It's a different story when the engine is on its first fire up.
