A connecting rod for an internal combustion engine consists of the ''big end'', ''rod'' and ''small end''. The small end attaches to the gudgeon pin (also called ''piston pin'' or ''wrist pin''), which can swivel in the piston. Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rollingelement bearing, in order to ...
Assuming that JLMCCUAN''s rods (or a similar set of rods) don''t appear I''ve done the math on the various different combinations of parts. I''m only shooting for 350hp right now but with good pistons and crank, I''d rather not spend significant money on something with only half the power capacity in the middle of them and kill the good parts.

To that I would add squareness as a major concern. Without a jig to guide the reamer Let''s say I sweep a dial gauge in my drill press chuck on the machined face of the conrod bigend bore (same way you tram a mill). Assuming this machined face is square to the bigend bore, I can adjust my drill table to get the rod square to the quill.

This will be the big end of the rod. Move " toward the opposite end of the rod and drill a 1/4" hole for the small end. then, using a 1/2" centercutting end mill, drill the 2 holes for the big end side radius. Next use a 1/4" ball end mill and hollow out the side of the rod. Then use a standard 1/4" end mill to cut the sides of the rod.
Next the conrod was returned to the 4jaw chuck and the bevel side faces were turned. The through hole drilled in the bigend bearing meant that set up was easy and it ran true from the outset. When the conrod was clamped on the crankpin for the first time it was a little tight although could be rotated with some force.
