So I’m back in the shop, I’ve learned that the duster has 276 gears in the rear end from being an automatic car in its past life, I miss quoted the cam I have, it’s the high energy 268/.454 cam, been out of the game sorta speak for a while. Really exciting getting back to it. Speaking of which, got the old 340 tore down, been sitting in an undisclosed location for about twenty years. Sad! I know. Every thing looks really good, but. I found some potting on the cylinder walls. Was just going to get some gaskets clean it up. Now it looks like a bit of a different plan?
