When I put my motor back together I will leave out the smog pump and a/c. My ? is what do I need to do to delete the smog pump? Do I not reuse the pipe that goes from head to head in the back? I assume so. And that's pretty much it right? Then all I need is a shorter belt? like a 73.5 right? I tried to piece this together with old posts, but it's not working.. Thank you..
