Usually happens when the rings butt, removes material directly from the ring face. In this case because the rings are designed to push against the cylinder wall when the fuse is lit there could be to much pressure with the early timing. With the C16 fuel you could fire pretty early without detonation. But then again I could be all wet.What is scuffing?
Rings would be sacrificial may not show up on the cylinder wall right away.So the only scuffing is on the ring? And not the cylinder wall? What about the side of the piston above the ring?
Then the timing issue is out the door. Your right it makes no sense. But I do not believe ring butt. Never heard of locking out at 38. That's tough. How did you start them?None of this is making sense to me. Our 409s had the distributors locked out with 38'. I'ld be looking at the ring lands and the rings themselves....could be a ring flutter issue. Piston rock is a problem inherent with a W
Fired right up. Used a mini gear drive starter
I don't remember... don't think so. Maybe Dick can tell us. Just remember it was easy to startSeparate switch for ignition?
Dave probably nailed it, separate switch for ignition, get the engine spinning and then flip ignition on. I'm not a fan of locking the ignition out but I never ran a drag only car before just street strip. Seen guys lock them out that run roundy round.I don't remember... don't think so. Maybe Dick can tell us. Just remember it was easy to start
Mega cam would bleed off enough dynamic pressure also. My cams are probably puny compaired to yours.Nope never got it cranking and then fired the ignition...no I never had a street/race car. Just full on race cars... they crank started with 14 to 1 compression

Did I have that box on the car or did you add it?MSD Timing Retard Control box. Takes out 20 degrees of timing until the engine exceeds 500 RPMS.
Ah, the magic 18 degree number.MSD Timing Retard Control box. Takes out 20 degrees of timing until the engine exceeds 500 RPMS.
