Connecting Rod Length Chart

Connecting Rod Length Chart - Measured (all are approximate or nominal): Web race engineering stocks the following connecting rods: Side beams may or not be machined. Web as a rule, connecting rod length can be employed to tighten or spread the rpm range between peak power and peak torque. Web connecting rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft. Web rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft. This number can have a direct effect on power, torque, engine efficiency, and piston wear. They say an engine is only as reliable as its weakest link. This is an impor­tant function in matching engine performance to the vehicle and its specific racing requirements. Also, download the pdf file.

Web By Larry Carley.

Web a connecting rod is measured between the centers of the crankshaft journal bore and the piston pin bore. Side beams may or not be machined. Find the model and year in column 1. Measure the inner diameter of the connecting rod's smaller hole using the caliper's inner jaws.

Measured (All Are Approximate Or Nominal):

They say an engine is only as reliable as its weakest link. The connecting rod length factors into the whole equation, but it isn’t the basis for what will give your engine more horsepower or better durability. Also, download the pdf file. If you build the same 350 with 6.000˝ rods, the rod ratio would be 1.72.

Connecting Rods Connect The Pistons To The Crankshaft In Internal Combustion Engines.

Web as a rule, connecting rod length can be employed to tighten or spread the rpm range between peak power and peak torque. Web if you’re building a stock sbc 350 with 5.700˝ rods and a 3.480˝ stroke, the rod ratio would be 5.7 (rod length) divided by 3.48 (stroke), which equals 1.64. But if you are building a 383 stroker with 6.000˝ rods, the rod ratio is 1.6 due to the longer stroke of 3.750˝. This is an impor­tant function in matching engine performance to the vehicle and its specific racing requirements.

Find The Motor Family Table:

Rod ratio is the length of a connecting rod (center to center) divided by the stroke of the crankshaft. Divide the number in half. Web connecting rod ratio is the mathematical relationship between the overall length of the connecting rods and the stroke of the crankshaft. Move right to columns 2 through 6 for the dimensions.
