Where can I find decent pistons for a /6? If I can't get a good used short block I will need to get some decent pistons for my old block. I have 2 /6 blocks. I have the 80 block that knocks horribly, and the 84 block that has sloppy cylinders. I would opt to fix the one with sloppy cylinders since I am scared of the one that knocks. I would need pistons with 30 or 40 overbore. Any suggestions? My Mopar Site! Mark71GTX@hotmail.com

If the top end (cylinders & pistons) of the 80 engine is real nice, I would seriously think about swapping the 84's crank and one connecting rod into the 80. (swap-out the con rod the bearing spun in) You can have a good running engine for the price of a gasket set and the cost to swap a piston onto a different rod. ( to be honest, I would also replace all the connecting rod bearings with a new set, that's just good insurance) As for a set of decent replacement pistons, Enginetech has some nice ones. Their number is listed in the "Slantsicness" HRM article, here is the link: DD HRM Slantsickness - Last Page

Thanks Doc. I am a little scared to use the 80 block. It had water standing in the oil pan from where the previous owner let it rain in it after the head was removed. I know the water stood in it for over 6 months. When I drained the oil it came out solid clear water for what seemed to me a VERY long time. I am afraid if I pull the main caps I will see they are pitted. What do you think? Other than the problem I mentioned, the 80 block had tight cylinders and the pistons looked great. My Mopar Site!

Did water get into the bores? See any rust? Does the engine still turn-over freely? If the water did not pit the bores or stick the rings, you should still be OK using this engine. If water gets in through an open distributor hole or the lifter galley oil return holes, it goes right to the bottom of the pan and does not hurt anything. At this point, just take the 80 engine apart and check things out, you have nothing to loose if it's already a "knocker". DD Quote: : : Thanks Doc. I am a little scared to use the 80 : block.

The cylinders are nice with no rust. I have actually started it. It runs fine and will idle, but has a VERY audible knock. http://communities.msn.com/MarkandVelana Mark71GTX@hotmail.com

Post subject:	re ring kit?
If I "do the Frankenstein" on my /6's I guess I should get a re-ring kit for it then right? What about the ones you see on ebay all of the time? Would that be a good kit to get, or should I just get one from my local machine shop? Thanks for any advice and all advice so far! http://communities.msn.com/MarkandVelana Mark71GTX@hotmail.com
