You're wasting your time trying to sort it out on motor. Cam and TC is a complete mismatch; I don't care what they told you it "should" flash to on motor.
I have my doubts about that TC ever working if it's flashing to only 3300 on motor yet "slipping" 14% (is that at the top end of the 1/4 mile?) on the 150.

 

In my data logs, I can see my SS3600 flash to 3800 and sit there until the car catches up to it.
I have a much smaller cam. 226/230

Data log shows a lot.

 

What's your cranking compression?
Do you have enough P/V clearance to advance the cam?

 

That's at 200-300ft before the finish on the 150 shot (7200rpm and no more gear). My last converter flashed only 2600rpm on this cam, truly think this cam is killing me. I know the TC will need to be tightened up any which way to spray.

 

You can't tell everything about a cam just knowing the .050" numbers and lift, but as long as it is installed correctly, I have my doubts that going to a milder cam will do much for your quarter mile times. My best guess is that you mighty pick up 5 hundredths or so in the 60' and probably lose MPH in the quarter. With a trap speed of 95 in the 1/8 and 120 in the quarter, I would say you only have the horsepower to run 11.20s in the quarter with a good 4000 RPM stall.

I think you are getting to the point where you have to decide between optimizing for N/A performance or for Nitrous performance. You will have to choose a stall converter based on your direction.

 

The G6X3 is a bigass cam no doubt... but it performs. 235/244 .647/.612 111+4. LSK/XE-R lobes. From a valve events perspective, it's very similar to what I have. And with a very loose NA converter, it has no problem exploding out of the hole.

 

It needs at least a 4000-4400rpm flash speed IMO and less rear gear, something around a 4.10-4.30 for that cam.

Either that, or the cam needs less overlap, and a later opening exhaust event.
