#70712, "Compression Check...."


          

I was just curious to know about what exact reading I should get with a rebuild on the compression?? I know it would be in the 200's somewhere but I dont know what exact number it should be looking for.

Hard to tell without your compression ratio but here are some specs:

Stock Motor (9.6 to 1 CR): 170 - 225 psi (max of 25% difference between cylinders)
Rebuilt Motor (8.6 to 1 CR): around 190 psi

Hope this helps,
Kurt

I believe with a 10.5:1 CR rebuild, you should see somewhere around 225-240. Not 100% sure since my rings were installed by a moron and my 10.5:1s are netting me some lower stock numbers. emoji

Oh yeah. Moron here = me. emoji New Total Seals go on with the new head. emoji
