Hi I am new to wanting a diesel i currently have a 5.7L vortec in my truck with 127k on the engine and 300k on the body. Ive always wanted a diesel but I dont know the route to go. I would love some expert opinions, on the best direction to go for the truck. I recently decided that I didnt want to get a motorcycle instead i wanted a diesel in my truck. I dont know much but the information i would like would help me out. I would like something with a little power maybe a 6bt naybe a 4bt depends what I can find. I have been seeinf that there are conversion kits to fit tbe 4bt and the 6bt to convert to a 4l60e tranny.
