My question is: will a Cummins ISB 4.5 fit in the Blazer? I don't want to install a lift. Any help is very...
  2. Cummins 6BT / 5.9 Conversions
    I have a 98 Chevy with a 89 12 valve going into it, instead of buying a tos and bracket can I use one of those tps delete kits for a 12 valve and wire it into the trans controller? Or does the 4l80e need to have a real tps?

    I am finally taking the plunge into the 4BT swap. I have learned quickly that the venture is not for the faint of heart. I am looking to get out under 7K. I purchased by 4BT in 2011 and 4L80E the same year. Then it sat in my garage as a dream that would not die. Ahead to 2019. My...

    Hello everyone, first time posting here on 4BTSwaps. Long time lurker though. None the less, I am sure many of you are far more knowledgeable than be when dealing with a cummins lineup of engines. So I figured I would post a question here. Currently I have a K5 (actually an M1009) with a 6.2...
