Sometimes it's the things you overlook...

So, I thought I may have wiped out a lobe on my camshaft. Number 5 and 6 header tubes were not getting heat in them ( small block L.A.) Pulled the drivers side valve cover off and turned the motor over with a remote trigger. Rockers for number 5 were moving just fine... So I started to rack my brain on why they are cold. Turns out.... when I had to pull the 4 speed out for a noise issue I had, I took of the distributor cap and rotor ( Mallory Unalight ) upon reassembly of the cap and rotor I didn't have the rotor fully seated causing number 5 and 6 not getting spark! I was relieved that I didn't wipe out the cam but mad at myself that I overlooked such a simple thing.
