WTB MC 45 parts - Bob LeFevre - 12-22-2019
Hi guys, looking for a piston for a 45 bored 40 over to 2.205. Also need a head shroud for same 45. Any help is appreciated.
Thanks, Bob

Bob, I think you meant 2.205". Stock bore is 2.165" You can use the 91 series pistons in your 45 and they are actually a little better than the original type as they have a better exhaust side bearing arrangement and they are a true 9 port piston. The 45 9 port layout used a full 360 piston and fed the boost ports through the third port passage as they removed the partition. If you use the 91 series piston you can fill up the third port passage and gain a little stuffing.
Terry Ives may still have new 91 series pistons in th size you need.

Thank you Steve, you are correct a little fat finger typing and poor proof reading. I’ll contact Terry. And thanks for the 9 port info.
