The pistons are cheap but they need to be MACHINED for Valve Reliefs....AND they need to be done right!!!! Not like the BUTCHER BJR!!!
The pistons are around 100.00 and the machining is around $180.00 depending on where you have it done at. These are CAST pistons from a 318 Truck engine. The Comp Height is 1.675 which puts the piston at 0 deck after cutting about .012 off the block and deck Height at 9.588 WITHOUT milling the top of the piston!! If the block needs more than that to square it you can adjust the Head Gasket thickness for your desired compression. I need to pull the box off my parts shelf I forgot the brand, I think they are Silovite but I will verify that!
From what Brian was telling me at IMM Engines you could just offset bore the 318 block and use an OFF the shelf piston for a 360 where you have many choices.
