3- 156psi
4- 169psi
5- 160psi

In the compression dept maybe. Bearings...only time will tell with them.

Ive used nothing but synthetic oil, changed every 2K. They should be ok...i hope..

When I did my cam install the cam bearings were not that loose at all..

The compression ratios are pretty good for that high of mileage.

thanks man, feels good to hear that(you have no idea)

i dont what to compare them to. is their an "good" to number to compare them too?

i think stock they run around 170-175 psi, i could be wrong tho.

i did one around 80k miles....165-180psi for me... i would like to do a leakdown test to really find out though...

im also using a full synthetic 0-30 oil too. Im sure if i was using a thicker dino oil it would have made better compression...i would think the thicker oil would help the rings make a better seal.

Where those dry or wet readings? Pretty good for that mileage.

dry or wet? I unplugged the fuel injectors, so....i guess dry

your compression readings will be different than a stock #'s because of your cam and your mileage. you are with in 3-4% so you are good to go there as stated. bearings could possibly be a problem but if you have good oil pressure and keep oil changed on a regualar basis then id say go with it. FWIW i have a 148K almost and drive it like its stolen. she is starting to puff some oil on decel so i am assuming its rings cause i have new heads( less than 7k) on them so its not valve guide seals. good enough of a reason to do a 370

Oil on decel is usually valve-seals. With that mileage though it could easily be rings or the PCV system sucking under vac.

no PCV anymore thought that was the problem also. could be valve guides seals but doubt it the heads were brand new when iput them on. i would say its the oil ring letting it get by. the new motor should fix this problem

dude there is a guy selling an 02 motor outta a WS6 with 43K for 1800 bucks

you should jump on that deal now b4 someone else does.

i have an 6.0l block and l92 heads in my garage need a few more pieces still

my car was makin some nice compression as well, i have 140k on it..and when i took my heads off the cylnder walls still had a nice 60* cross hatch and not to much of a piston ridge.

So i take it if im not burning any oil, and getting good compression, I have the green light to buy some nice flowing heads instead of a new shortblock.

Not burning oil=bearings are in decent shape

good compression=good effciency(sp?)

I change my oil every 2K miles, and up keep my fluids and buy nothing but the best fluids, etc.

I guess im ready for some nice heads, and tires...what do yall think?
