Do eagle rods have a power limit?? Ya know like a stock block is good to 700ish HP. I ended up with the Eagles and now have second thoughts,,,

One of my H beams twisted at 850 HP. In the trash they went I now have Oliver I beam rods.....

Strength limits are based on bobweight, rpm , and power adder usage. So for sure you have a lot of bobweight being a Hemi and power adder to boot.

I have seen motors using eagle h beam rods at 1000HP with the upgraded L19 rod bolts. I've also seen plenty of motors using them at 700hp. IIRC eagle does list hp limits for the rods, but nobody could say for sure as 700hp at 6500rpm is a little different than 700hp at 8500 rpm.

They aren't the most expensive rod so it would stand to reason that quality control and metal consistency may be worse than more expensive rods, so if you were looking to get to the upper limits of their rated hp you may want to consider something higher end.

I called Eagle about this same question, and gave them my part number, and he said it was accounting to which bolts that are used, as to the power limit.

My buddy went with Oliver on the last 2 builds, He never had a Eagle rod problem but he wanted to up grade , he now has a nice display of a couple busted Oliver rods on his desk now.

If it were me, I'd get some better rods in that hemi! A big ole heavy hemi piston making a lot of power w/ a blower on top...that's not something I'd even consider using an Eagle rod in.

I would like to check out a set of these one of these days.

i built 2x stroker 400's in quick succession last year. 1x used the Eagle rod with the L19 bolts, the other used Molnar Rods. The 8x Molnar rods weighed 1kg less than the Eagle Rods in just rod weight alone. Both motors are running real strong & the Eagle rods looked fine to me, but in future i'll be going the Molnar route. Can't beat that kind of weight saving on a engine i'm going to beat on.

OK,you guys motivated me to call Eagle.These rods are supposed to be good to 1500 HP with the l19 bolts.My blood pressure is back down now

Are you saying that the Molnar rods, all eight of them, weighed 1000 grams lighter(around 35 ounces) total than the eight Eagles rod weighed total?

That's the first time that I have ever heard of a eagle Rod being better than an Oliver rod. If You're busting them, then that's one bad ass motor!!

Everytime I hear the name Oliver I go back to the Silvaliant thread where he found the pin bores were crooked in his 501" small block. For a high dollar rod I don't feel that was acceptable thing to discover.

Not at all

I bought and installed a set of Oliver billet steel 7.1 long B Chevy style rods in a blown gas street hemi motor I built for a customer in SO. CA some (10 to 15 yrs.) years ago, one of the rod caps did not have the rod cap bearing tang machined deep enough to allow the back of the bearing to seat against the rod cap I caught it and they paid the over night Fed Ex air freight to return it to them and fix it and return to me in three days, that was just the beginning of the disappointments I had with them on those rods
The ARP 2000 bolts must have been from different heat treat batches, I wanted to use a stretch gauge and found that those bolts varied more than 30 Ft lbs. to get them to stretch within the .0005 stretch specs that they furnished me with
When I contacted them about the stretch spec.(nothing furnished with or on the instruction sheet about the stretch lengths) they told me to use either 30 or 45 ft. lbs. and 30 degrees more rotation on their special custom made ARP 2000 rod bolts I told them I didn't have a tool for my torque wrench that would do that, they told me to imagine a 360 degree wheel or a picture like that in my head and to go from there
Needless to say I bought one set of rods from them, never again

What rods did you use before now?

All of my Oliver rods came with torque to yield specs and bolt stretch specs, for all the different Rod bolts they use 👍

15 Years on Eagle 6.385 Chevy rods and not always treated nicely...............

I've got a set in my 605 with the ARP2000 bolts. Bob weight is 2393.5, which is pretty light for a Hemi. With the small heads it was at 853hp. The motor never see's 7000rpm and I have a rev limiter. Never had a problem.Dave

I've been rolling the dice running Eagles (7.1, Chevy ends) w. ARP 8740 bolts in a NA 540 for 6 years (440-1s, 13-5:1, 800-825 hp). They've held up (street driven). And to think that the shortblock was built for truck pulling. They spent money on the O-ringed Mega Block, Callies 4.5 crank, Wiseco custom pistons...but for some strange reason they went cheap on the rods & bolts. I had uneasy feelings about the Eagles back when purchasing the all new shortblock, but wasn't smart enough to do the upgrade then. It's time... before the block and crank are turned into worthless scrap metal.
