I was given several months ago Speed Pro Pistons. I was told they are a part of a 383 setup. However I cant find anyone that can help me with what Connecting rods I need to make this complete. I have listed below what is on the box.

H859CP STD.
Minimum Clearance 0.0010
383 Chevy 12cc Dish
Bore Range 4.000-4.001
Skirt Size 3.99875 +/- .00025 Inches

Any help would be great.

 

You should measure the compression height. Or you could use Google to search for the specs. The problem with specs though is that the part may not match them. Or, you could mock up with existing rods and measure.
