This is my fault for not paying attention while teardown. I have an 86 Chevy 292. It has pistons with a D-shaped dished top. There are no notches on the pistons, but there is an "F" embossed on either side of the wrist pin on one side of the piston. Is that the front, or do I orient via the D shaped top, and if so which way should it face? Thanks.

The "F" goes towards the Front of the engine. If the rods were never separated, the oil squirt notch at one side of the rod would then point towards the cam.

Yes, the "F" goes toward the front. 292 rods don't have oil spit notches in them, but the bearing tang side of the rod goes on the drivers side of engine.

thanks for correcting. Yea, rod bearing tangs are on the opposite side from the cam.

cool, thank you very much. I've not seperated the rod/pistons so that will be easy to complete this step of assembly.
