Installing new distributor

[High Bidder]

I am upgrading my distributor in my OMC Ford 302.  The new distributor is shorter than the old one. It engages the oil pump driveshaft 5/16". Is that enough? the old one engaged about 3/4". Or do I have the wrong distributor?

The only way to go on this one is buying the original OMC one or if unavailable a sierra  one. Anything else, specially on a such a crucial thing  as turning the oil pump is asking for very expensive trouble.

5/16 Of an inch should turn the pump without a problem. but why take any chances with losing oil to the primary parts of your motor. the only way I'd use it would be if i couldn't get the right one. you may have to pay more for an OEM part but remember you get what you pay for in most cases.

It looks like a Sierra is the only way to go. No originals are available. When my crank broke it must have bent the distributor shaft.  It keeps getting a misfire on different cylinders. I contacted Pertronix but when they said I must have installed the wrong heads that is why their distributor doesn't fit I knew the tech was a moron.
