Stock 89 -95 block just upgraded.....vortec heads, 480 roller cam, intake, etc... Had to tap block nipples for lifter hold down plate...changed distributer gear to match cam. Distributer goes in smooth but won't drop into oil pump shaft!!! Tried bumping motor over while pressing down on distributer...tried turning oil pump shaft to line up...all help is appreciated.

Boy thats a ***

Has that distributor ever run in that block?

Have you tried with a long slot srcew driver to leave the oil pump shaft in the direction of the #1 spark plug as it would be on the distributor. Then see if it drop in. Good Luck. Hopefully some of the other guys will have some input.

is the intake properly centered over the distributer opening??? probably or you might have an issue dropping it in.. can you check the gap around the housing with the distributer part way in.. it might be hanging up on the step just before the collar..



do you have a spare oil pump shaft...  many parts stores sell the IS-55E with the steel collar.. they don't even know it..

if you have one.. insert it into the bottom of the distributer.. see if it seats fully.. not hangs up on a burr on the flat blade on the shaft..




a thought just crossed my mind...   what happens if the oil pump shaft came up slightly with the distributer...  it could be not seated on the oil pump slots stopping the seating of your distributer..

i should also add..

that when i have an issue dropping a distributer in... with the #1 spark plug out... i find compression.. set the damper to the base timing... drop the distributer in with the rotor pointing in the proper direction...    if it does not drop... i use my remote starter to spin the motor while i push LIGHTLY down on the rotor while its spinning.. this will usually seat the oil pump shaft in the bottom of the gear allowing the housing to seat...

i then establish #1 compression again..  set the damper to base timing..  turn the housing to align the tips of the pickup coil and the reluctor. this is where the distributer is going to fire the coil.. i can lock it down and the car or truck will start...

since that is a TBI distributer.. before putting it in.. please pull the rotor off...   examine the reluctor magnet.. the second layer on the shaft.. if the magnet is cracked.. replace the distributer..

this is a aftermarket reman unit that really improves on the stamped steel reluctor design

Thanks for all help but I finally got it...I ended up pulling dist gear off to see if dist would seat in oil pump shaft...it did so I figured cam was too far forward or back...loosened rocker nuts and it dropped first stab...boy was I happy after 3 days of failure...finally heard the built motor run with ear to ear smile Laugh
