500 series BME's at the same length, 6.700" are about 40g lighter then the 396 series from the comparisons I've had over the past few weeks.

At 9000+ rpm with the foot to the floor, they would not survive a 500 mile race.

I was leaning on using a BM rod next season in a circle track application. I called and talked to Bill to pick his thoughts. He said they had mixed results. He did not recommend a aluminum rod in that type of racing where you go wide open, then let off repeatedly.

In a drag race app i have over 100 passes +dyno time on a set of 426 series rods at 1000+ hp. This series rod can take much more hp than this.


Eric, what series rod do you use?

Just curious how much do these rods weigh?

BME rods (396s) in my hemi have around 200 runs on them. A "run" is up to 20 seconds long in mini-rod pulling. I see them going "forever", with only 3.75" stroke, no more than 9,000 RPM, and probably a little shy of 1,000 HP.
