Almost time for the machinist!
Also! Make sure you can get rings for the pistons. I ordered a stroker rotating assy for my 318-390 and mancini or I couldn’t find rings for .040 over bore. Luckily the motor didn’t need +.040 over. I just wanted to be able to use 392 emblems. I usually bring machinist a crusty block and have them clean it. They charged 500 for clean, mag, bore, hone parallel deck and cast blast. He will then take the pistons and hone to close I also go through with a die grinder and get any casting flash out of there and then 2 or 3 go rounds with the engine gun and mineral spirits. You should always have the bobweight balanced too, but also take into consideration that OG mopar was NOT within a few grams of each other but more likely ounces apart on factory balance
