Thanks Otto and everyone else, If I only had more time and energy. I'm a small business owner and have a full time job. My original builder is back on track. He's a reputable inline 6 specialist who has done this for a living for decades. I have more faith in him than me for sure. Also, I'd rather drive/use my truck sooner than later with my limited time. I will be adding everything to the block and head once it's built. This is my second go around. My 1st block suffered a cracked cylinder wall after 2 days of driving.
