Stopping the knock: Lower compression and ported heads...

moper said

I've just been lurking on this one for a while.

You could have lightened the weights (as I suggested) and reset the timing for a higher initial, then retuned the carb, and been done. you were that close. Once I saw you were ignoring that, I figured it's not worth trying anymore. You wanted to spend more, port the heads, etc etc etc. I'm glad you like the way it runs now - but you were <> close to solving it without additional expense.

I read this and wondered if you left out something.
If I set the initial to anything less than 16 degrees, the idle suffered. If I ran the total up to around 30 degrees, the car knocked. I suppose that I may have been able to run the timing curve locked out but at what point would I set it ?

As with before, RRR has refused to respond to the question I asked several other times. He wants to bash me for not following advice but when I ask for clarification, he has nothing to say.
Regardless, the engine no longer detonates. Now I'm on to tuning and making the car a bit more "user friendly" for road trips. This includes quieter mufflers for sure!
