Hey I'm sell a Brand new set of 347 Probe SRS Forged and Coated Pistons. And Perfect Circle Preformance Nascar Performance Pistons Rings. The slugs will make a 306 but you have to use aftermarket I or H Beam rods. There 30 over 10 to 1 compression Forged Pistons. I paid $160 to get them coated on top to help prevent detonation. And make them run cooler. A little trick that I learned. Selling because I went with 4.125 Piston size. To make a Big Bore 363 motor since I got a Boss 302 block. They brand new in the box never bolt on or ranon a motor. I'm asking for the best offer with rings sleaves and pins. But don't low ball me. These Probe SRS Pistons sell for $512.99 plus shipping. With no Piston rings. And no top Piston coating. Send me a pirvate message. So I can recive it via my E-mail. Being I'm not on Stangnet everyday. Thankyou Ladies and Gentelman.View attachment 70677View attachment 70678View attachment 70678View attachment 70678View attachment 70679View attachment 70680View attachment 70681
