Trying to set the timing per everything I've read in just about every thread on the subject using the search. (Complete engine specs below).
Vacuum wise it's hard to get anywhere past 7 or 8. I don't get anywhere near 15 or so unless I really rev the motor. I know the cam may have a lot to do with that. (This is vac capped at dizzy. Pulling from the tree from where the brake booster normally connects.) Should I see more, even with that cam?
It seems like no matter what the timing is set at, the car feels best with a baseline idle of 900-1,000 over the published spec of 800. Could this just be my build also? This is timing from the gun. My gauge is apparently way off. Gun will say 800 when the gauge will say 500.
If I drop the timing down to 12, she just straight wants to die.
If I leave the timing at 16, keep the RPMs around 950 where it "feels" best, and then hook my vac back up, and give her some throttle, I'm well past 50 on the marks by the time I hit 2,000 rpm. No way I can find 32-36 @3,000rpm.
Am I doing something wrong here, or with this type of build, is this what I should be seeing?
