I tried this in the engine forum but did not get much feedback so I thought I would try it here

#1 137psi
#2 145psi
#3 137psi
#4 140psi
#5 135psi
#6 130psi
#7 150psi
#8 140psi

These numbers seemed ok to me I was told not to worry if they were over 100psi. What had me concerned was the diff between #6 & #7. 20 psi seemed like a large diff. The truck is a 95 F150 351 with somewhere around 150K to my best guess. The engine was replaced once the OD has 218,000

Those numbers are close enough that with gauge inaccuracy they are fine.

You should see the numbers on my 290K 351 F350 crewcab.

Those numbers look great! You will not find too many new vehicles with numbers that are better!

The Ford spec is a maximum variation of 25 percent. Your 20psi min/max is only 13 percent. It looks very good to me.

Well I was thinking about selling it but now maybe i will just invest some more into the cosmetics that it needs and keep it awhile.

thanks
