Valve Timing Questions
#201
Wait for the tune, you don't want to romp on it with incorrect fueling. Go too lean and you'll regret it.
Btw, you don't need break in oil for a roller camshaft, just for flat tappets. You will want to snug up the header/manifold bolts after a heat cycle. Pay special attention to the collector bolts, esp. if you're still using the stock collector flange with only 2 bolts.
It's going to be a nice little bump in power. Should keep you happy for a month, then you'll want more.
They always want more...

Oh, I figure I had to break it in since the entire cam and valvetrain is new. I was just playing it safe. I did break the cam and valve springs as recommended. I'm going to keep her in the driveway for sure until I get my tune. I have way too much invested to make a mistake now. I'm going to check the headers tomorrow and make sure everything is snug still. I've ran 3 heat cycles of 1500rpm for 10min and even though it's not tuned and running rich at idle it starts right up with no hesitation. I would say it purrs like a kitten but it thumps like a rabbit lol And yes, I know I will want more but that's what my 408 I'm starting to save and build up is for

Yeah it was at +4 when I tightened it down the first time before the tune. The only thing I can think of is maybe it wasn't tightened down good enough. I'm just trying to figure out what number works best with my tune now. +4 and it would stumble and die when I would come to a stop. I'm thinking I may have to try 0 or possibly -2.
