Tuning For Detonation

Rusty what am I missing. Why are you so bent on have 20* of initial timing.
I have never had to dial in that much timing to tune an engine.

I'm not. Not at all.....It's simply that the engine responds very well there. You know the old saying.....the engine will tell you what it likes. And it does. That's all I was sayin. I may have to leave it back at the 15 mark.....which IS actually 20 initial. It's just by chance I pulled 20 out of the hat, because that's where it seemed happy. It couldda been 12, 25 or whatever.

Well see here's the thing......normally engines with low cranking pressure numbers will want a LOT of initial. I'm beginning to think that's what we have here....that the cam is actually DOING what I hoped......but that the initial tune I had right off the bat just sucked. I'll know a LOT more when I take manifold vacuum measurements and when I get a good compression gauge. I mean **** man, 40 total mechanical on a 7:1 motor would probably ping. lol
