It's my OPINION that total method is rotten for street cars. Again, MY OPINION, It's the lazy way to do it. If idle quality doesn't matter, have at it with total method. Just like you think my method is less than ideal. More than one way to skin a cat. One MAJOR issue about total method, how much mechanical advance is in the distributor. Is mechanical 28* or 14* or 22* or 16*... you get the idea. Idle quality varies greatly with a range like that. I sure am glad that MSD includes those useless mechanical advance limiter bushings with their distributors, cause according to some, they just don't matter (total timing group).
One thing you can't argue with, if the engine picks up rpm as you advance the timing at idle, it's running more efficiently. Same as using a vacuum gauge to set initial, picks up vacuum, the engine wants it.
--------------------------------------------------
If you have only 7" of vacuum at idle, that cam is pretty dang big with lots of overlap.
Good luck with it.
Right on!!

the sec. idle speed screw is under the sec. lever. virtually impossible to adjust with carb. on car. The holley manual (hanes) I have says turn it in till it just touches the lever, then 1 more turn. I replaced my set screw with allen head screw (lowes) so I can adjust while carb. is mounted.

9 times out of 10, if the idle speed drops significantly between neutral and drive, the problem is in the distributor, not the carb or converter.
If the mechanical advance springs in the distributor are too light, there will be just a touch of advance at idle speeds of 900-100 RPM (remember - factory idle is about 700 RPM). When you put it in gear, the idle slows just enough to let the advance spring pull back, which removes some of the timing, resulting in a bigger drop in idle RPM.
Since you have a converter which will flash to 2500, there is no point in having light springs in the distributor. I would install two medium springs, and reset your timing to 36 degrees @ 3000 RPM. (w/vacuum advance plugged off),
I think a half dozen of us told him that in the first thread, but guess we didn't type loud enough....

Grab distributor and twist it clockwise... it needs more initial. If the engine picks up RPM when you do that THE ENGINE WANTS THE TIMING, PERIOD!
Put 16 on it at idle, turn the idle speed down to 850-900, reset mix screws to highest vacuum and see what it does. You'll have to change the mechanical. been through this before, read the other post you started. Don't drive it until you alter the mechanical advance.
IMO, Total timing method is a rotten method for timing a street driven car.
Only time I have a tune up on a car like what you currently have is if it needs to be smogged!
Positive you don't have vacuum leak issues?
but that won't help the idle drop problem if his advance springs are too light and he's partially advanced in park, and the idle drop when putting it in gear pulls more timing out.

I had the initial around 18 and there was no deviation between park or in gear timing. It stays rock solid at 18 in both situations.
Idle drop already addressed!
