Reading plugs

grjammer said
I'm sure the rings haven't seated yet with the short run time. RC12YC plugs were supplied by 440 source for their stealth heads. I almost have it out and should have it on the stand later today. Going to fix the rear main seal, and remove the intake as well to re-seal and get a look at the cam and lifters. Hopefully I don't see any major issues.
Cam is a Sealed Power CS661. (292/309 110 LSA) . Degreed about 107 LSA so tweaked it with a gear set to install on 110. Addons are the Stealth heads and Tri-Y's.
Pistons are Speed Pro 350NP, with a compression distance of 1.99. I didn't get an in the hole measurement but last year I figured about 8.5 cr. Hopefully it is enough for a mild cruiser.

Well the 12 is right on the edge of being too cold for that CR and your cam.

Please explain your engine break in procedure.

If you did the 20-30 minute cam break in the rings had better be seated.

If it takes 500 miles to get the rings in you might as well pull it now and have someone that knows how to hone a cylinder fix it.

The rings should be in by the time the cam is in.
