Well I finally got to investigate farther, I do have an LA cam in this engine.
Could you please send me the info as to where I can get a stock profile cam and lifters.

Try these guys:

When I needed one, no new cores were available.
I ended up getting a reground piece from here:
https://www.deltacam.com/

When you get the current cam out of the motor, I’d be interested in knowing if it had a part number on it.

I have had a few poly’s over the years. 62-67. 1967 was the only year to have hydraulic lifters. 62-66 that I had all had solid lifters. Up here in Canada anyways. Of course the USA had the LA 318 for the 1967 Mosley year. Kim
 
Well I finally got a stock cam and solid lifters from falconglobal.com My Thanks to PRHeads info.
Installed this afternoon but now I can't find the lash settings. Damned if I know where I put them. Memory was used too much when new. I'M going to keep looking for the settings.
The bottom cam is the wrong one , the top is the proper cam.

In case your adjuster screw question hasn't been answered, the later Poly 318s all had adjusters that did not have lock nuts. Retention of the adjuster is accomplished by the thread interference between the adjuster and rocker. You can have and use lock nuts. It's just that they aren't really needed.

I finally got the 66 Cornet 440 running today:
My Thanks to everyone who had suggestions.
Many Thanks to PRHeads who, came up with the solution : The cam was the wrong one, during the rebuild they found the cam was wasted, and replaced it, unknowingly with an LA cam. I found a cam online and damned if I can remember who I got it from, but I installed around the first of June then got sidetracked,I had to replace the lash adjusting screws which were friction locks with jamb nut locks since I couldn't get the rocker shafts out to the heads to replace the rocker arms without a lot of extra work , ordered a new set of lifters (solids) since I had some of the originals missing, I was lucky I was able to slide rockers arms to the side and R&R the push rods and lifters.Now comes the fun figuring out which brackets go where to install the A/C comp. which I think is trashed, Oh well I only agreed to get the damned thing running.
Once again Thanks to everyone!!!!
Frank

Sorry I've been so long getting back to you. One again thank you for your help!!!
Life interfered with getting the car back on the road.
I did check the original replacement cam, no part numbers!
I replaced the rocker adjusters and added lock nuts since they did not feel like they had enough interference. The engine is running great and sounds like it has a mild lope, no problem. Next came the front end Ball joints ect. then the fuel tank replaced, then the horn wiring AFU, now its looking like the brake line to the rear may need to be replaced, will find out later today.
To be truthful I would not have taken this car as a gift and would not have worked on it for anyone else.
I wish I still had my 64 Sport Fury 4speed ragtop, engine replaced with a low mileage 68 440 It was the most well mannered car I have had until I bought a 2018 Grand Caravan this thing has getup and go that sometimes scares me but handles better than my Lincoln town cars from the past.
There were so many cooks in the kitchen on this before my son-in-law ask me to look at it, at the time this model would have been in an independent shop I was working on diesels and had never even heard of a "Poly" 318 but had worked on everything from the old Flathead 36's up and everything else up to 1965 Hemi's.
