Brain,

He's running stock stuff. This isnt a big *** cam.. it's got less overlap than a cc306, which is an easy daily driver with tuning. There's 6 or 7 guys running the same topend/cam with stock gears in their daily drivers. It isnt bad at all, but I'd always suggest a little shorter gear.. hell you've got a .5 OD with a 6speed, there's no reason not too .

1fasasz, we usually try to keep it under 11.33:1 since there isnt enough power going over 11:1 to matter. Hopefully he can dyno again now that some fuel system stuff has been fixed

Disable it?

Lloyd,

Sunoco GT 100 took care of the knock problem on the dyno. I still get a blip of knock counts every time I shift on the street. I'm pretty well convinced it's garbage noise so I'll set my KR to zero at the track. I tuned AFR to 13.0 to 13.2 across the RPM range. I had AFR dialed in on the second pull. I was rushed for time so I didn't fool with timing. I was seeing about 32 deg at 2600 and it ramped up to 39 deg at 6400
