Compression questions

What is the normal range for compression test on a '94 7.3?

And are the blocks the same in a '94 and a '99?

I was told the ford spec is between 400-425. This will drop depending on your elevation. I just checked mine and it was 350 right on the dot. I am about 4500 feet. I think the blocks are the same between the 7.3s
