I ran the compression test and the results are between 180-190 lbs. does anyone know about what compression ratio this is. Thanks

 

Looks like you've got good compression, assuming all your cylinders were within 10 lbs. Don't be confused though--cylinder compression has nothing to do with the compression ratio. You'd have to tell us what engine you have before we'd know the compression ratio. And that's assuming the engine is stock, meaning no aftermarket heads, pistons, or milling.

 

355cid engine heads are world product s/r torquers 67cc, .125 domed pistons. does this help?
