so the marking on the second compression ring was just to distinguish between top and bottom compression rings?

From Hastings Website

CORRECT COMPRESSION RING INSTALLATION Back
   
 
 Ring installation instructions are placed in every set of piston rings Hastings Manufacturing Company produces. These instructions should be read each time before the piston rings are installed on the pistons. Listed below are the general rules for the installation of various types of compression rings.

Rings having a "pip" mark or dot on the side of the ring must always be installed with the "pip" mark or dot towards the top of the piston.

Rings with a bevel on the inside diameter but no "pip" mark or dot must be installed with the bevel towards the top of the piston.

Rings with a groove in the outside diameter and no "pip" mark or dot must be installed with the groove toward the bottom of the piston.

* Rings having no dots, bevels, or grooves can be installed either way.

I've figured out that it was the rings that were causing the smoke. Would the rings also cause the engine to act retarded? stumbling when i hit the gas and only having some power at higher rpms? Thanks for all the help

Okay, I guess I wad backwards on the angled edge, but i was correct on the marking going up. Im not sure about the power aspect  could be the oil robbing it of power, but it could also be carb, tuning, timing problems.

would a backwards fuel filter hinder performance?

Let me rephrase it. How much would it hinder performance, since you obviously know everything.

Well don't get snippy and you'll receive a better explanation.

Depending on the filter you will have varied amounts of restriction of the fuel flow, and the filter will plug up and be useless sooner. Some have almost a check valve effect where you wouldn't get enough flow to do much more than idle. Either way it can be hard on a fuel pump and you would most likely have a significant decrease in performance. That, however, would not contribute to the other problems you're having, so you didn't pull the engine for nothing. Performance-wise, when you get it all back together put the filter in the right way, dial in your idle mixture and timing, and check for vacuum leaks.

I'm sure you'll get it figured out, and it will be worth it when you are done 8)

When I first put my motor in my truck, I had no oil pressure. Found out I had forgot a plug on the back of the motor under the driver side head, and the one above the oil filter. Pulled the head off, plugged the hole, plugged the one above the filter, reused the head gasket and put it back together. Still no pressure. Had to pull the engine out and call the machine shop. They put a metric sized plug in one of my oil passages and blocked the oil flow. Got it back together, into the truck, and got water in my oil. Replaced the head gasket I reused, flushed about 6 quarts through the block and tried again. Water in my oil. Replaced the intake gaskets, flushed another 6 quarts. Water in my oil again. Replaced the intake gaskets again and made sure I put a thick bead of silicone around the water ports and flushed oil through her again and finally got the leaks fixed. Ridiculous. Some times things just go wrong. You'll get it figured out.
