my 95 3.4 has 145k and i just did a compression check, and it came back with the following:
#1-200 psi
#2-205
#3-190
#4-170
#5-190
#6-210
my question is: are these good numbers , i plan on rebuilding so should i look into high compression pistons or would the gains not be worth the $$? and if these numbers are low what kinda compression should i be looking at after a rebuild (honing re-ring pistons, etc), basically im gettin my engine ready to do some n/a work (cam ,p&p, etc) any info such as what cam to get or anything else will be appreciated
thx

 

Not the best, they should be within 25psi of each other.
Get a crane flat tap mechanical cam for. search you will find it.
You sould see no less than 205 on all cylinders after the rebuild.
