Psi on compression is good but the 2 that are 10 down could be an issue. Typically you don't see numbers that are all the same all the way across.
I have base timing set at 12 degrees before top dead cylinder and I added 24 totaling 36° total timing...On 87 fuel back down initial to 10 to 12
Ported vacuum
Your listening to some that are sending you the wrong way. I've been doing this 40+ years and usually get to fix what the experts screw up
Full on advance by 2500 not 3500
This is hard to answer this. It depends on what your car wants. Major factors are cam shaft and torque converter and drivetrain gearing.I have base timing at 12°, so I guess I'm going to put 22 at 2500, making total to make it 34 total timing.
Right now I'm adjusting the idle mixture screws using a vacuum gauge. When I'm done with that I'm going to do total timing, reconnect the distributor to ported and take it down the street and back and see how it does.
Should I go ahead and throw in the heavier weights in the distributor since I already put in the lighter springs or should I just use the weights that came with the aftermarket HEI distributor ?
