BIG set screw???
I had my engine machined and partially assembled when I went to put in the distributor the gear hits on a large set screw in the engine. Wondering what this screw is for and can I just turn it in deeper so the gear clears?

I would almost bet that its the plug for one of the oil passages. They have a hex socket type head, chances are that the machine shop had it out. If you have the water pump and timing cover on, you'll probably end up taking them back off to screw it in.

no not the oil pump rod it sounds to be the plug. I actuly got it out through the distributor hole Im going to grind it down alittle bit then I'll try to get in back in but i was wondering if hte plug was screwed in to a certain depth, or just locktite in in as deep as i can get it.

hold it! there is no way that you should have to grind down an oil galley plug to get the distributor in. something is way off! i strongly recommend a book to help you get your engine together, "HOW TO REBUILD YOUR FORD V8 351C-351M-400-429-460" by Tom Monroe. it's not perfect but it's pretty darn good. anybody near you that would know what they are looking at?

The plug in my block was petty close to flush. Some guys have a .030 orfice drilled in the middle of those to oil the distributor gear, which isn't a bad idea. But I agree... it shouldn't ever have to be gound down.

Tom Monroes book says that the plugs in the front of the block are shorter than the plugs in the back of the block, is it possible that your problem plug belongs in the back and one of the plugs back there belongs in the front? i didn't think there was a plug around the dizzy gear that would give you trouble but i went out and looked at my block on the stand and there is a plug right behind the gear alright! mine's way in far enough too though BTW.

Thanks for the input grclark. I dont know if they flipped screws but since I have the engine all put together, I am working through the distubter hole. I removed the screw (that was a job). Now I think I am going to grind off the head about 1/8 of an inch,drill a small hole in it to provide a little more oil to the gear and then locktite it back in as far as I can (hopefuly flush).

Gallery Plug
It should be noted that if the plugs are in the wrong holes the end result will be the rear plugs will leak.This recently happened to a customer at my freinds engine shop. The front plugs have a taper seat and are not regular pipe thread hence putting them in the rear will result in a leak. I just finished rebuilding my 400 and the plugs are definitely different. hope this helps
