Appreciate the info guys. I wasn't expecting an exact number just a ball park figure. The reason I'm looking at buying these is so I can avoid having to ship the block and or heads to a machine shop to be decked. I don't have one ine local, and I assumed it would be cheaper to use these pistons then to try and find and use a machine shop I have no history with.
The motor is a 76 318 out of a M880 has been rebuilt within 2 years of me getting it. Crank has been turned and its been bored .020 over. Has summit brand headers has a stealth intake 650 eldelbrock and summit .441/.441 .218/.228 cam.....I'm wanting to step up and use a howards .510/.510 .247/.247 cam
