My 350HO swap is at the 1,500 mile mark. I'm still experementing with injector sizes and throttle bodies. Question: Can any amount of tweaking to TBI properly feed my motor? No, I wont switch to a carb, I really want to keep my TBI.

Your Holley 670 should be more than enough to supply fuel to your setup. JPrevost is running a very similar setup and he's trapping at 104 or 106 I believe. My *** needs to get a 2" tbi but Im flat broke.
You would really benefit from a chip which you seem to have addresed in the sig lol

If you pull less than 1.5 inches of Hg at WOT than you have enough TB or a crappy intake. 3 PSI or less of exhaust pressure at WOT is another good thing to have.
