Best parts for a bone stock 4.0 rebuild
Posted: March 11th, 2018, 7:02 am
So my grocery getter/highway cruiser 99 WJ is in need of a new engine. It is still driveable right now and needs to continue to do so.
I have bought a core engine to rebuild and then swap out in a weekend. I have it all torn down and everything is at the machine shop getting checked for cracks, etc..
I am going to be doing a bone stock rebuild on this engine. I do not need or want any performance mods, this is a 2wd WJ and all it sees is back and forth to work, and it is what I take on long highway trips. I can get between 22-24 highway MPG and do not want to change that. (my YJ with a stroker get 10.5 mpg)
So my question, is what are the best quality stock style replacement parts I can get. I will be using a new genuine mopar factory replacement camshaft, but the rest is up to debate.
I will need the following:
Pistons and rings
Bearings
Timing set
Pistons I have found MAHLE/CLEVITE 2243415 and SEALED POWER H825CP. Is one better than the other? Looking at pictures alone, the clevite pistons "look" like they are cast and machined a little better than the sealed power pistons, but that is looks alone. Are there any other options that are better than there? (remember, best quality stock replacement)
Timing sets we have a few choices. There is melling, sealed power, and cloyes. The melling and sealed power look just like the factory timing set I pulled out of the engine, while the cloyes looks noticeably different. Same as above, looking for the best quality stock replacement, I will be keeping the thrust plate.
Bearings I assume the norm is usually clevite? That is what I am running in my stroker in my YJ and they seem fine. They show two different choices, A-series (aluminum) and P-series (tri metal). I assume the P-series is the better? I can not remember what I have in my stroker other than the box saying "clevite 77"
Also cam bearings. I have durabond in my YJ's stroker, seems I remember when building it, those seemed to be the ones most people say were the best. Is that still the case?
Thanks for the help.
