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

1996 F250 crew cab. Hypermax intercooler, Gearhead tunes, 4" exhaust, 6637 intake, Autometer gauges, Dana 60, 6.0 cooling fan, Built e40d, Firestone airbags, Full Force stage ones more to come.
