I am collecting a few parts, as my engine/trans combo will be pulled this spring to get properly mounted. It is a good time to finally re-do my exhaust. I am planning to go back to stock manifolds and make a simple exhaust. I do see the big restriction on the 3800 rear manifold and looked into the ZZP PLog. I am wondering how many people on here have bought the new style that is currently for sale. Any cracking problems? Any dyno results to verify the claims of more HP? Any issues with fitting the stock heat shield or dip stick?

thanks

I have used several of the SS version PLOG and have had no issues. Big improvement over the stock manifold.

Good enough for me, given that you are one of the most experienced swap guys on the forum. I will order one

Any suggestions on what gasket to use? Is their crossover pipe of any value (I don't care about appearance as much- just want good flow and reliability)

Cross over I believe is just a coated stock pipe. If u have the extra change then doesn't hurt to help with the heat. Stock gaskets. Reuse the ones on ur swap unless they r messed up for some reason.

The SS plog's are better.. the regular steel logs rust bad at the welds quickly and blow out/crack there pretty easily.

I had a stainless zzp plog on my grand prix since around early 2009, you will have no issues at all with the stainless version... The newer style mild steel is probably better than the earlier ones but they have still been known to crack.

Well since you asked, both.

I started out with the one that came with my motor which is the smaller block mounted scroll type compressor, it fit snugly to say the least.

Then when I received my AC lines, they had the wrong fitting for the AC comp, so I went to the JY and got a series 2 pump with brackets.... that one actually hit the plog, so i googled it ant pappy had the same problem on his build so he "clearanced" the compressor to fit.
