351/400M compression?

[MMeier]

Buddy has a 79 Bronco with the 351/400 in it, has a solid miss all through out the RPM range, changed wires and plugs, no change. What should a compression test show on this pig? Has a small RV cam, and headers, otherwise stock. TIA!

not much probably around 135, don't know for sure. Look for one in the 60 range to give you a miss. I had picked one up with a burnt valve and have another with a blown head gasket.

as aak said---probably burnt valve---
