Hey
@Montytm26 Very nice looking build you've got going there. I'm not fuel injected so I can't comment about that but your process sound reasonable to me.
Regarding timing, I'm running a Clay Smith 6474 and when I first fired up my engine for cam break in I was probably running it around 12 degrees advanced or maybe even less. I have an HEI distributor. When I decided to get the car on the road to put some mileage on it I was probably running +20 degrees initial and overly rich. I need to put my timing light on it again to find out where it's at now.
I have just over 2000 miles on my engine and for my setup and the limitations of the small log head, it's about perfect. I have backed timing down a little over time. I suspect I'm at about +15° initial advance. My vacuum advance is +10° and my mechanical advance probably kicks in somewhere in the teens around 1,500 RPM and is all in before 3,000 RPM. I am running one gold and one silver spring so one stock spring and one light spring. I ran two light springs for a while but it surged at parking lot speeds (1st gear on my T5).
I'm on a small log intake and my idle varies depending on level of warmed up. When it is warmed up enough to drive, my idle varies between 500 RPM - 600 RPM. When it is warmed fully and running at optimum, my idle is about 900 RPM. I think if it was fuel injected and an aluminum head and intake, I wouldn't have such a wide variance and I could probably set a smooth idle at about 600 RPM - 700 RPM.
I hope that gives a little insight.
