| I am rebuilding a 383 from a 1967 Coronet to be installed in my 84 pickup. After priming the engine with oil priming tool which went as expected. When I started putting the intermediate shaft in I can not get correct alignment. Then I notice the cam shaft has moved toward front of engine. I assume this happened when I pressurized oil system. Is this normal? |

Very unlikely that oilpressure alone would have pushed the cam forward.
Did you turn the engine during priming?
Just pry the cam back, bring the engine to TDC and align the slot in the intermediate shaft inline with the cam.

Location: Netherlands | It can only go as far back as the timing sprocket allows because that's riding on the block/front cambearing surface.

yes, just in case thats off... i thought it is as the chain cover should limit the foward movement too, there isn't much free play, i think.
