Until it stops bogging! Whatever it takes...
But here's the deal; do not expect this baby with 2.72s and a low stall TC to take full throttle from a standing start.What I would do is take it out in first gear to 3000 rpm and stomp on it. Let it pull to 4000 and slam the secondaries shut. If it will do that without bogging, I would repeat the test at 2600, and going to 3600.If it will take that, I would repeat the test at 2200, going to 3200.And so on; always reducing by 400. When the bog shows up, THEN I would tighten it up just enough to eliminate the bog. Sooner or later you may reach a point where tightening it more, just makes it open way too late at the top. Now you have found the lower limit of flooring it. If it happens to be 2200,or2600, well then you are gonna need a higher stall TC to let the engine spool up to the magic number.
So I guess you haven't had time yet for the compression test?Or to hunt up the cam specs? Those numbers can tell a lot about why this is happening. For example if you had 160 plus psi, this should not be happening. But if you have 120 or less, well then this is to be expected. At 140, things should be better than what they are.
Still, not knowing the cam specs, and not knowing the cylinder pressure it's anybody's guess as to the what and why of it.
