I tried to run the RC10YC plugs in mine. It didn't like the cold plugs.
I run RC12YC4 plug, I run a .045 gap.
It's a .020 360, zero decked pistons, solid cam & out of the box Eddies.
Runs 11.30's, with a best of 11.27. I put a set of plugs in at the first of the season & midway through. Running an MSD 6AL box & coil.
