Timing question
I have a 97 Ram 1500. This last weekend I swapped my 5.2 for a 5.9. The 5.9 was from a '96. It had the computer with it. I used almost all of the sensors from the 5.2 because some of the plugs from the 5.9 didn't match the 5.2's wiring harness. I also had to use the 5.2's fuel rail but with the 5.9 injectors. Since the 5.9 had been sitting awhile I removed the oil pump/distributor drive gear/rod so I could prime the engine without turning it over. I was very careful to mark everything and get it back where it was. The engine is running and sounds great but it lacks the power it should. I checked the timing with a light and it is a little off TDC but of course moving the distributor changes it a little but not enough. So I'm thinking I need to take it to a dealer and get it synced. Does this sound about right and does anyone know approximately how much it costs. Thanks a lot for any suggestions.

The oil pump shaft may be keeping you from getting an exact alignment.

I'd pull the cap and get everything lined back up where it needs to go. Make a note of where the rotor is facing (if it's one tooth before or after where TDC should be). Pull the dist and move the pump shaft with a screwdriver and re-set the dist to see if it's at the optimum spot it should be (where #1 is on the cap with the engine at TDC).

Thanks for the reply Warlock. I had already done that and you're right I was off by one tooth but now if I turn the distributor too far one way or the other it kills the engine. Before it would hit the intake. So I think I'm where I should be.
