Yeah, I guess I am being hard headed. If I want a car with a chevy v8 I'll buy a chevy.
My Buick GN has a Buick engine in it, and that Buick engine is what I'm working with. I've got over 10 years tied up on tying to turn this hunk of yard art back into a car, I'm not even going to consider doing a powertrain swap.
It sure would have been nice to pull the timing down across the board (and hopefully see the knock disappear). With a distributor it would have taken me about 2 seconds to run that test. And learn if that that fixed it.
As of now, I'm waiting on a TT chip that (hopefully) will let me pull timing. I can't do a damn thing until I run that test. If it fixes it, then I know my engine build needs less advance than the average build. If it doesn't fix it, I had to go through a bunch of unnecessary bullshit to run a simple test and then dig deeper.
