Can I Dome A Piston to Increase Compression?

[RedGas]

IDK on filler. I bought the 4047 because I researched it and it’s the closest alloy to what’s used in pistons. Apparently the highest silicon content of the filler rod alloys.

Ive got a few pounds of it if you need.

No idea on performance. I agreed to do it for nothing for a member on AS at the time. Guy had a build thread going.

The member flaked out on me, posted 1 post with the piston in the saw, and disappeared. I even had to eat the shipping costs he had agreed to pay.

Thank you for the offer. I might just give it a go with 4043 or maybe some 4943. That sucks about the guy blowing you off...no good deed goes unpunished!
