Rod weights 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.

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.

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
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

Piston pin 118 grams
