If you want to protect the huge investment you are getting ready to make, the first thing I would do is throw that factory oil pump gear in the garbage and get a Pro-Drive or equivalent. I used AEBS sleeves in my race motor. Excellent product and they are great people. I prefer Manley when it comes to rods and valves, again i am bias, due to this is what i run myself. Also, if you get the AEBS sleeves, they will get you a good price on Ross pistons.
