Looking for more pep off the line

Let's see if he's actually serious about resolving the issue. 4 pages of generally solid advice. Now time to do the work.

One more time. initial means nothing without rpm. "total" means next to nothing without rpm.
Don't go wide open throttle until the baseline is established. The one way that the engine can be damaged is detonation uner heavy load (heavy acceleration in upper gears). Pull the spark plugs and see if there are aluminum specs on them. If so, that's from the piston.

You can't use a little of one procedure and mix it with a little of another procedure.

If you want to start with WOT, then you have to approach it the other way. Set up timing at a high rpm, like 2800. Then work back to other conditions.

Alright this took a minute but I did some work on the car. I bought the FBO plate and set it at 16 with initial at 18 for a total of 34, I put in heavier springs to hold the timing back, it came in way too early. I can’t run the vacuum advance because it sends my timing thru the roof and it stumbles and pops out the exhaust.

I ran a compression check and all cylinders except 7 look good. Spark plugs look like they’re ok too. The car does not have a steady idle nor a steady low rpm, at higher rpm it evens out.

I’m currently rebuilding an 850 Thermoquad so I can ditch the 600 cfm Holley.
