Had 80 passes on my Groden rods before breaking one in the water box. Destroyed everything but the bare heads. Now I run Carrillo steel rods.
Just out of curiosity how many 1000's of RPM were you at in the water box?

I've had good luck with aluminum and will continue to use it. Like I said earlier, my BME's were in the car from Jan.2001-Oct.09 without a problem. 75-100 passes a year. My next set will be GRP's and I hope for the same results.

It's interesting how many negative opinions there are about aluminum rods. I can't count the times people at the track fire up their race motors, rev the heck out of them cold, go to the burn out box cold, run 42 degrees timing etc, and when something goes wrong, they blame the parts. I'd guess the guy with 2400HP ran al uminum rods, and changes them regularly. Just a guess, but even if they're steel, he changes them regularly.

Good point about running the engine hard when cold. BME wants a minimum oil temp of 125.
I never run my engine hard unless the oil temp is 160 or higher.

Well FWIW I make 1050hp at 7600. When I run the car all out I shift at 8300, going througbh the traps I am at 7750. Having said that I usually run the ca on the stop, which means I let go of the trans brake button, go on the stop immediately at 4300+- and am on the stop for 4.8-4.9 seconds. I come off the stop as slow as it will open and cross the traps at 7350 usually. That nets me 10.90 in the mid 150's.

Then there's always the guy who blows a brand new engine in the water box and blames it on the aluminum rods. 
If my brooks rods can take 10500RPM when I over rev it, then aluminum rods don't break because
of a hi rpm burnout. lol

 We are building a Indy Maxx 540" with GRPs as we speak,we have two 500" with BMs that have been together for quite a few years also.

I have run BME's for 600 plus runs for nearly 20 years now. Never a failure. Bill Miller also advises you to never leave the rods torqued for long periods of time during storage. If you plan to store your car for months at a time without running the engine, you should also loosen the rod bolts and re-torque when you are going to be using the car again. 
I don't know why this is, so don't ask me. Bill Miller just recommends it "HIGHLY" Seems he doesn't like them torqued for long standing periods.
I have always done this and had great results.
I am currently using GRP 6.535 aluminum rods in my 542" B1.. We will see how these work..
Chris.. 
We were told on BMs to flood the bolts with 30#oil What's up with that?

I really said that comment for the shear fact that he is a stick racer and IIRC I have heard his motor wound up somewhere around 9000 RPM(by ear) of course. Gotta think that is hard on just about any part or material out there.
In the waterbox: 7000-8000RPM
When I got them, the Groden rods looked less beefy than the BME's we took out after approx 150 runs. Called Groden to make sure they would be OK. He said "my rods are the strongest made" I took him at his word.
I'm slowly building a 270 something ci brand X motor that will spin 10000+. I'll put aluminum rods in it, but they won't be Groden.
BTW I love the sound of the high winding small blocks

Alot of people say (including Koffel) that aluminum rods are more forgiving when over reved.

When torquing BME rods , he says to one step torque the bolts and use lots of 30w oil for wet torque, also make sure all flat washer surfaces are wet

Indy cylinder head convinced me that the aluminum would act as a cusion or shock absorber when used in a stroker motor.
They said to use steel if I like but then I'll be going through rod bearings every 100 passes with a stroker. I kinda doubt that last part.
I've been chasing bugs out of my car for 5 seasons now, (VERY VERY low budget and very few passes each season) and have used aluminum rods for all 5 seasons. I wouldn't be afraid to put 300 passes on my bme aluminum rods.
I'm putting out approximately 800 to 900 horsepower and shift at 7000. I have a 500" typical .060 over 4.15 stroke 440. Never had a bearing failure but I should probably pull it appart and check em but I'm going to get one more season out of it before tearing it appart.
Like someone else said, some results may vary.
Good luck,
Wayne
