Swapping just pistons

[Porno Joe]

Just a random thought I had here at work-

Since the weak spot in my LBZ is the pistons, is it possible to simply weight match the pistons and swap them, say with a set of fingers pistons, in frame? Like pull the heads and oil pans, unbolt rods, pull out, put new piston on. Done.

Is something like that possible?

motor has to come out to do it or drop the trans but yes, i know of many who have concidered that before. the factory motor isnt a balanced rotating assembly as it is already so doing what your saying shouldnt change much.

Now I could be wrong. But aren't the Mahle motorsports pistons that Fingers uses lighter than LBZ pistons. You would have to take weight out of the crank I believe.

they took weight out of my crank when balancing my rotating assembly. but a guy locally did his without pulling the motor in his

Joe id just save yourself alot of headaches and just pull the motor you will be able to work on it so much easier and in the end you will have the job done faster.To drop the upper oil pan with motor in the truck you have to drop the front diff and to drop the front diff you have ti remove the center link......just pull it,tranny would have to come out also.

Don't know on the piston swap, but it really doesn't take long to get a motor out.

pull the motopr..... save yourself the head ache.... rebalance the motor assembly for peace of mind

Oh I'm not doing this anytime soon.

I have a spare block sitting in the corner I could start building if my money tree ever starts blooming
