Ok, so I want to fire the engine today on the test stand for the first time. I understand that I need to run it for 20mins at over 2500 rpm for cam/lifter break in.
I dont have a seperate tach, so what would be the min hook up to run long jumpers to the car, and use the in-dash tach? |

Like i mentioned, turning it over without plugs i am getting 5-10psi oil pressure. Damn thing wont turn over with plugs. I suspect my starter may be below par. Thinking i might get an early 911 starter, as it looks like they have almost double the power.
I just hope i do not have a bearing thats installed wrong. Pretty sure I dont. Anyone know how much torque it would take to turn over an engine with new bearings, new pistons and cylinders? Without plugs, that is. |

Anyone know how much torque it would take to turn over an engine with new bearings, new pistons and cylinders? Without plugs, that is. Sounds like a classic wire/connection problem. What are you using to try and turn the starter? jumper cables with a battery, or did you get the proper cables for it? |
