I moly coated my pistons (below the ring lands) skirts and ceramic coated the tops above the ring lands. The prep work is very time consuming. I used products from Techline. Don't forget to bore an extra .001 over to compensate for the coating.
You will need acetone, 120 grit aluminum oxcide, sand blaster, oven 400 degrees, good touch up gun, masking tape. The people at techline will tell you exactly how. I think you need a resale license to purchase from them. GOOD LUCK
I've hot tested my engine, every seems OK. Now i'm heading for the dyno.
BBF 557 cu in probably 700+ hp and about the same in torque.
