I am putting my BRAND NEW IN BOX MMR1000S 5.0L rotating assembly up for sale. This kit is rated to 1,000hp per the MMR website. I had them notch the pistons for bigger cams and they balanced the assembly as well. These are all extra charges on top of their current price of $2699.00. The pistons are for a .020'' over bore and its an 8.5:1 compression ratio. Im asking $2,350 for this kit. Thanks for looking!
