Hey gang! I love this forum, it is the best and has the most knowledgeable and passionate idi people around! I have an 1986 6.9 idit. It has low miles, approximately 120k-130k (odo broke for a little while). The truck is my current DD but I am having a hard time keeping up with all the issues. So here is the plan. I'm taking it off the road, and I want the suspension, brakes, electrical, and every other major system fully restored. I dream of putting a 5spd manuel tranny, but would be happy with a rebuilt automatic. As for the engine, I want about 300hp out of it BUT it needs to be a reliable engine as I plan to resume DD duties until I die!! I'm not interested in racing, just want more oomph. Several questions emerge as I consider this project. 1. Is 300 hp achievable while still maintaining DD reliability? 2. I love manual transmissions and want one but I don't want to sacrifice reliability to achieve it. Is this swap possible with said results, or is it a perpetual tinkering problem? 3. I live in Alabamas gulf coast and I can't find a shop willing to do any work on this engine, I'm willing to ship it to the right place, is there anyone who is competant with the engine work? Someone who can achieve 300 reliable horses? 4. If you have any insights into things to look out for, or to add to my truck please share. I'm in the planning phase right now and hope to begin the process this summer.
