What did Dan do with it? Just wall decor?
I'm not sure what water cross over they intended when they made this cover, but factory one would have never fit. I may still hit the block off plate with some 2000 sandpaper to satin finish the base and only polish the ribs. Like the valley cover.

Got the rotating assembly installed. Next is the cam and timing chain. I have the AP oil pump drive rod without the retaining dimple on the rod. So it could get pulled out through the top. Is it enough of a concern to bother buying the one from Nightmare Performance that has a retainer function similar to a stock rod? What are the chances it would get stuck to the distributor ? Thanks

Personally never seen a rod get pulled out. No engine i've built had the retaining dimples and i pull dist often to prime oil pump. Just make sure that the rod and dist fit is smooth and isn't too smug of a fit.

There was mention on here of a guy breaking his AP distributor rod. I'm wondering if anyone else had troubles.

IMO buy the Nightmare shaft, I am. I know of a few guys running it with IA2. Cheap insurance, why even deal with the thought of it coming out ?. Not using the rod I got for free and buying Nightmares.
I have a billet Dynagear shaft that came with a SD 80lb pump. I will use it with the 60lb pump going in the 461. It has a little c clip on it to prevent coming out the top when distributor is pulled. The one Dan provided for my 455 had it also.

I don't know what happened to it. I bet I could have gotten it back when I talked to his widow getting my stuff, very nice lady who remembered me.
One thing he had that would be valuable to the Pontiac community were his notes. He documented "everything". He even checked deck heights on Pontiac blocks and found slight differences in runs. Had this giant C micrometer to do it.
