The Callies Compstar LS1 specific connecting rods. Our base engines were coming with the Eagle H beam connecting rods. The Callies CompStar rods are a lot better in our opinion than the Eagles. The Eagles are a good rod but now that the Callies are available we have decided to use them. Mostly for the reason of them being on center, where the Eagle rod was a standard SBC. Also I forgot to mention that the Callies Compstar's come with ARP 2000 rod bolts, the Eagles come with ARP 8740 hardware.

Awesome, sent you a pm about getting these in the motor you are building me at the moment...

 

How much hp are the Callies rods able to hold?

 

I have been using some Callies rods and am roughly 650 -675 ish hp lvl and they have held up to multiple nitrous runs, I bet the limit is alot higher than this though.

 

Sounds like a really good deal on a 347 shortblock then......

 

whats the rod weight, and compared to stock and others
