Anyone have a list or know about what Eagle, Callies compstars, Scat and Crower Rods weigh? Im plannign a motor build that will be a street strip motor, see 11-1 -11.3 static compression and 200-300 hit of spray. I need a rod that will hold to the absue (Im sure any will) but dont want to get a rod thats overkill and adds to the rotation mass, its just not needed. Thanks alot.

Let me rephase, will the eagle or compstars be strong enough for my needs?

I agree !

The weights of all of our rods are listed HERE

BigDB

I dont understand how the weights are listed, is that for 3 different rods? its X/Y/Z

Sorry, I'm so used to dealing with these, I just assume that people can read my mind.....
Example: 6.125" LS1 618/ 447/ 171
618 = Total wt.
447 = Big End wt.
171 = Small End wt.

I'm doing some updates on the site this week, I'll re-format that so it's self explainetory.

how do the compstar rods compare in weight to the stockers. Ideally, what about the piston rod combo compared to stockers
thx

BigDB

Id like to know as well, I know a forged rod will be heavier then stock but forged pistons will be lighter, combating the effect of the rod. Also arnt the stock rods 6.125's? Im staying stock cube and want a replacment rod.

How much do the stock rods weigh?

I'm not sure of the average weight of a stock rod, but NHRA lists the minimum rod weight for a super stock LS1 at 593 grams. For the sake of argument, I'll use that weight. The stock rod length is 6.098", and most aftermarket companies round that up to 6.100".
Here are the numbers:

Stock rod 593 grams
Stock piston 441 grams
Stock piston pin 150 grams
Total 1184 grams

Compstar 6.100 rod 607 grams
Matching forged piston 430 grams
Piston pin 118 grams
Total 1155 grams

Compstar 6.125 rod 618 grams
Matching forged piston 428 grams
Piston pin 118 grams
Total 1164 grams
