Msd pro billet in a small block 360 backfire at idle

MSD bushings are in crank degrees.

Black bushing is 18* on the crank, IIRC. The bushing I was making were in crank degrees also. One of the quirks of MSD and actually a bit less confusing for most people. "Math is hard!"


Dammit, my bad. That is correct. Got my arse out in front of my head.

Did you find the MSD bushings inconsistent? I can run out and measure some of them and they’ll all be different sizes. Talking about the same color/size bushing.

I’m also not a fan of the springs MSD sends out. I need to source some so I can get what I want.
