Mopar Performance P5007412 Pistons - 05/24/21 08:59 PM
Hello everyone,
I recently purchased a set of Mopar Performance P5007412 Pistons and it seems like there is very little information online about them. They are listed in the Building Big Inch Mopar Small Blocks book as Pistons for a Stroker engine but that is about all the information that I have found other than they are discontinued. I am curious if anyone knows who made these pistons for Mopar Performance. They are forged aluminum and have valve reliefs cut into the flat top design. They are the standard bore 4.00 inch pistons and I would like to put them in a low mile 5.9 magnum block and possibly put a 4 inch stroker crankshaft in as well without doing any machine work if I can get away with it.
My question is, what is my Compression Ratio going to be? They have a 1.418 Compression Height. I think the valve relief is 5cc's? I would like to have 10-1 or less and plan to use this motor as a street motor just for fun. I have a set of New Cast Iron Mopar Performance heads with 2.02 intake valves that have been sitting in my garage for years so I would like to use those if I can.
