EAGLE SIR6123CB RODS

Supposedly the Eagle cranks and rods have slipped in quality. Everything that I bought was from the 90's and never had any problems. Need a lighter rod for a 318 motor that will be built soon with a goal of 400-450 HP with a rev limit of 6400 rpms. Will these rods fit my needs? I do have a strict $ amount. All other parts are on the shelf and ready for the machine shop.

There was an instance for the Car Craft guy, one of his rods shattered. I have Scat I beams, they were similar money and were 4340

Those rods have the reputation on breaking caps off. I would look at Scat on a tight budget. They have some very light I beams. Not sure if Molnar has anything light, but he has really nice stuff.

Scat 4340 I beams usually come in around 590 grams plus or minus...

I have three shops that have done machine work for me in the past several years. None like to work with Eagle stuff...poor quality control, poor reliabilty in those Sr rods, etc.

I have VERY limited engine building knowledge so I'm hesitant to even post in this section. That being said, last year I stopped by the local machine shop and saw a brand new Eagle rod in the junk bin. I asked about it and they said they were torquing the cap and the threads pulled out of the rod. Needless to say, I didn't get the best first impression.

Check out Molnar rods.... the ones in my W8 mill are tiny compared to the eagle that we ran with our W5 build.

Stock rods will handle that.

I've done stock rods before. By the time your done with the machine shop fees of mag, resize, bush, peen and good rod bolts, you have an old rod with a bill that's approaching new. Plus a lighter rod(depending on brand and model) is a help in getting to the power band faster. We are also talking about 40+ year old parts with thousands of cycles to live in a performance environment.
