Its me again lol

Ok, I'm gonna try to answer all the questions here and maybe give a better overall picture.
1: the cam ( XE256H) is installed straight up. It has 4* of crank ground in.
2: the pump was started at the top hole an now in middle, still had hesitation issue. I'll move it to 3rd hole and try cause that's super quick test. Middle is usual spot I put it in.
3: the 900 rpm is my personal setting, i put it there cause the transmission brings idle to 700 when in drive. But I have been considering making it 700 and letting drive drop it 500 rpm.
4: no the 20* made it a little worse, felt like it fell flat faster.
5: compression is 9:5.1 (.030 bored w/ 91' 308 swirl port heads ported and polished) comp spring, hydraulic lifters and comp rods. Hyperueretic pistons.
6: VA is adj. But is not hooked up as I was fixing the timing issue, with lots of help from yall. Also the edelbrock air gap intake blocks my access to the VA, thinking about takin a saw and cutting a 1/4 piece off the VA tube so I can at least put a tube to it.

First thing I'll start with will be the 3rd hole on pump. Easy to eliminate. I'll pull the carb after that if it doesnt work and checking the transfer slots as I did chem dip the carb after it sat for almost a year. I want to make sure I put the blades back on correctly. If all else fails, I guess I'm drilling.
