I am having a little trouble figuring out my (correct) compression ratio. Could someone please help? Mods are TEA Stage 2 5.3 heads milled 0.15, 3.622 stroke with stock crank, 3.905 bore with 6.125 compstar rods with Diamond flat tops Comp Height 1.315 Effective Volume -1.6cc, Cometic 0.40 head gasket, comp cam 612 612 240 244 on a 112 with 93 octane.

Thanks Alot
Michael

 

Use the search next time please, thats why we have it.Compression Calculator

Your heads are going to be about 61cc in volume.

 

Well I did use the search, but I keep coming up with different ratios with different calculators. I was just seeing if anyone could give me an accurate one.

 

Youre gonna be in the 11.2 SCR, 8.0 DCR area.

 

Thanks man
