I've been running AR3910 plugs for a long time now but my new 572 with B1 MCs doesn't seem to like them. Who's using what? 
Dick, I use either NGK 9's or 57CX's CPN-295 at Summit from champion. And the non projected long reach NGK's. I'll have to get you the number on mine, cause I don't have it here. How does the car work without an air pump?

So far no problem. 
I just clamped a K&N breather over the -12 bungs on the valve covers. When the rings start to go away I'm sure it'll be a different story. It'd probably make some more power with a pump but, oh well.
Unless I re-mount my radiator further forward there's not much room.

Thanks Scott and Tom, I'll get some of the NGKs ASAP. I used some 5672A-9s last year and didn't like them but maybe the new heads will.
Tom, no full passes yet without the motor crappin' so no idea on SG MPH yet. I'm borrowing a buddies spare 7AL3 and Pro Power coil this weekend for Jim's "Fire & Thunder" race. I'll make the first hit with my parts then if it still doesn't run I'll swap the box and coil and try again. Sure would like to get a SG pass or two. Hope I can get more than the 1 pass I made last time I went to Woodburn!
Did you see the You Tube vid I posted of the car on Paolo's chassis dyno. Look under the car. 
I did see it. The starter looks like it is gaining a little clearence, but mine has done that too. What do you have for jets and what carb? And what timimg? Checking all of you MSD connections might help, as well. I used to have issues with the moisture in that area over the winter corroding all kinds of stuff in my car. I'm sure it's something simple. I never used Autolite plugs, but if you are a little hot, or too fat or lean, too much timing etc, that might be causing you a problem. I'll be out there for the divisional at the end of the month racing my old car in S/C. Then you can watch me struggle.
