Default Compression test results. Head/cam forged motor

Got bored Saturday so did some preventative maintanence and a compression check.

All cylinders between 180-190 PSI except for cylinder 4 which had like 200, freak cylinder.

Motors still healthy, time to go put some more bottles of nitrous through it.

Figured id share.

Compression ratio must be a bit higher than stock. Those look like great numbers man!

My mods are in signature. I have diamonds and compstar rods. My rings are filled for a 200 shot and compression test was right at 160 for all 8 cyclinders. Engine has 1150 miles on it.
