Well I got about a 150 miles on my rebuild 1330 21253 ae pistons 10:1 comppresssion with a kent 266 cam.
I had the engine at the normal operating temp throttle wide open and checked readings after 4 cranks and after 8 cranks wich is about where the readings maxed out.

4 cranks
#1-165
#2-163
#3-165
#4-167

8 cranks
#1-182
#2-180
#3-185
#4-188
Then just for kicks i threw a little oil in 1 of the cylinders and i got like 240 after 5 or 6 cranks is this normal. And are these normal numbers for a healthy 1275

they look fine to me, but you really should quote units.

It's like saying "the piece of string is 12 long"

12", 12mm, 12cm, 12 miles... :X
