You guys with the 3.4 blocks, what numbers are you getting for compression test? 100-125-135-140-higher?


Still trying to find my vac leak here and this will be helpful.

I also sent a tech question to milling co. asking if the mtc5 is a steady vac cam, or flux vac cam


:beatsheadondesk:

iirc i was getting about 160 in each cylinder (on stock cam)

Thanks, I dont think the cam will change it, just the worn rings/milage on engine.

Anyone else?

I just ran a CR test the other day and I was getting about 190 on each cylinder. BUT, that's with dome pistons and (more importantly) new rings. Really, this info is a little irrelevant to most people here but just cause Dale asked for "anyone else"
