make sure to get the proper degree hone in that block. Im not sure exactly what ross pistons call for, but be sure to get that right. Also clearance the rotating assembly 3times, 7ms are finicky, also clearence the oil pump. Last but not least, check the piston ring end gaps. Once you finally get it fired and running let it idle for a long time to check for leaks. I overheated my new engine 1 time cuz of a damn coolant leak, and I got totally pissed.
