302 and 351 pumps and pans don't fit each other so that's kind of an apples and oranges comparison but good info for somebody with a 302 to have

I was able to use the stock pan with mine, I would have to verify the model but I believe it’s a Melling 68HV. I ended up getting a composite distributor gear so I am less concerned with stress on the gears. I only have a few hours on the engine since the rebuild but so far it looks good.

Not that I recommend a high volume pump, as the extra stress on the dist/cam gear for the fords is imho more likely to break than save your engine. However, I had to go back and check but according to my records I am running a melling 10833 - high volume standard pressure oil pump on my 83 ski nautique. It has the stock pan as far as I remember, I bought some later gt40 ones but they didnt clear my stud girdle, so I went back to the original. The block however is not from 83, it is a roller block so maybe 95 vintage. ?

With a 351 Pleasurecraft and the stock oil pan, you don't have to worry about using a high volume pump like say a Melling M-83HV because the pan won't fit with the pump in place,
The extra depth of the pump body keeps the pan from seating on the block up front where the pump is. |

I installed a high volume oil pump in my 302 I rebuilt for a 77 Skit Tique last winter. I’m sure a standard lump would have been fine, I just wanted to ensure I had good flow at high rpm’s. |

Yeah I was surprised to see the cork also!
Indeed rtv has been the solution for decades. I've also seen dimpling the rails done. |

I have heard in the past that Fords do not need a high volume pump, have you ever heard that? The only thing I question is their use of a gasket on the manifold ends, I thought it was standard procedure to use silicone gasket maker, they must have a reason not to use it. |

And they remark getting a new oil pump, but unclear if it's high volume or std

From my understanding of bronze distributor gears, it’s not uncommon for them to wear out in race applications. I am surprised there was no mention of changing to a composite gear.

Thanks Ken, that is a good read for guys who like engines.
When you have distributor gear failure you always need to check the oil pump to see if it is loading the drive shaft excessively. Turning the distributor is a no load situation but turning the oil pump can be very high load most often on cold start ups with thick cold oil. They might be asking that gear to work harder than it is designed for. Mark |

At least it was interesting to me and I figure MrMcD and a handful of others will probably find it interesting also.
Just to be perfectly clear, I know that boats don't run in the sandy desert There have been a couple of chewed up distributor and cam gear threads recently though. link |
