Going to have a 347. Stock crank, Callies rods , diamond pistons.
It's going to be N/A for a little bit, but it will have a rear mount build. Ill be running no more than 12lbs. With a 67mm. What should I gap the rings too?

Bump... Gapped the top to .022 and the second to .014. Will that work?

Nice! This post alone deserves to be a sticky! LOL With as many people who search and start new posts.

its on the tight side in my opinion. I'd go .026/.028 and have room to grow for more power down the road. I have no blow by issues at .030/.030.

good luck

I went by what the paper said with the total seal rings?
3.905•.0055 for the top
3.905•.0035 for the second.

Wiseco's same base guidelines said .024 for my turbo motor. After calling them and explaining what my build was they said 0.030" and .0055 piston to wall clearance (.0035 on the paper with the pistons).

It will work, just a lil tight.
