May have screwed up installing new cam. Need help!

I am going to jump in here and add to the complexities. First off for some obscure reason the engine gods to be back in the dark ages decided that cam timing should be done at TDC firing #6 and #1 on overlap never did understand that even when I started building engines 60+ yrs ago.

OK all the instructions to find #1 TDC are good to verify it and yes cam timing gear marks should be at 6 and 12.

Hear is the part you won't like. As this was done 2 yrs ago and sitting you will have to take it all apart and pull the camshaft and relube the lobes with cam break in lube fresh same with lifters especially now that you have been turning it over a number of times, I have lost a few flat tappet cams right after start up for this reason it is critical. Also after it is back together add one extra quart of fresh oil when adding oil and prefill the carb so it fires up immediately bring RPM up to 1500 or so for at least 10 minutes. The reason for this is load on the cam lobes is reduced that way, every new flat tappet cam will go bad right after starting because it has to break in, matching the lifters and lobes together, that is also why you never install a new cam with used lifters.

Good luck with your project find and verify the TDC location and do as I recommend so the cam will live, and one more thing not mentioned above after sitting with spring pressure on them all the lifters will be collapsed after this amount of time.
