Yep, P0308 check your #8 spark plug, connection to coil, wires, then pushrods. Swap wires from 6 to 8 to see if fault follows.
On timing cover at bottom right there is the cam sensor connection. It's big and black faces downward. Check the other 2 prong connection right in front of the cam...i think it might be for vvt.

I pulled the plug yesterday and found it carbon fouled. plugs and wires are new. but my CMP is this style but I found the eletrical readings and outputs relating to the sensor so I will be checking those tomorrow.

So update guys. While doing my tear down originally i noticed valve marks on the #1 piston. When I sent the heads into the local machine shop for milling and pressure testing everything "passed". During reassembly I accidentally switched which side the heads went on. Now I'm still getting getting misfire #8. No issue with #8 pre rebuild. After a lot of testing and checking plugs, wires, coils, compression and everything else the heads were removed and found #8 open with a bent valve. Which leads me to believe I was charged for the pressure test and it was never performed. Talked to a local mechanic buddy and in my state any diagnostic testing you pay for you are legally supposed to get those results. I never got my pressure results red flag 2...not tested. Thankfully It's a relatively easy procedure now that i know what I'm getting into. So to wrap this rant/update up...if you have knock marks.....double check and verify. Make sure your parts are truly tested properly. I even read somewhere that a guy stamps his initials in his heads before testing just as a sure fire way to guarantee he is getting HIS parts back. Very appreciative of all the knowledge shared and experiences during this rebuild. Sadly for me its now 0-15*. Time to blare the music and crank the heat. If anyone coming across this has questions feel free to message me. Im no ASE Mechanic but I can give tidbits of what i learned along the way.

I recently installed a DOD/AFM delete kit from Texas-speed and performance with new camshaft and lifters. Looking for best way to tune the motor or what Tuner I should use. Anyone ever do this before?

Many have done that. Get with Lew and get his tuning. Highly recommended.

He has said in the past, that if it will idle on its own on the stock tune, he can tune for them.

If it won't idle, he can't tune for them.

So it would depend on the cam. It'd be best to get with him and see what he thinks in regard to the cam profile and if he thinks its something he would do or not.
