They were the rod-of-choice for almost every blown-nitro machine for a few years. I believe the alloy was 2014, the same as the earlier M/T rods. 20-series alloys were developed by the British during WWII (named Duralumin), the first so-called high-strength aluminum alloy. 2014-T6 yield strength is 60 KSI (the 7075-T6 of BME rods is 67 KSI). For eleven seasons I ran early 2-rib M/T rods in my 900 HP/9,000 RPM 370 c.i. all-aluminum M/T blown-alky mini-puller hemi engine. I still have the set of 3-rib rods that I kept in reserve- never needed them.

Why thank you for the info, that is just the ticket. Very much appreciated!

Although there is no mention of 3B anywhere, here’s some pics from my copy of the ‘63 M/T catalog.

That catalog sheet is terrific! I'm trying to decipher the part numbering system. It's obvious that the last 3 digits represent the engine that it goes in. I'm wondering if the first 3 or 4 digits represents the raw forging that is used? BME makes me think of this since they have (3) forging sizes that can be machined to a multitude of different applications.

Just wondering.....

3B. 1963.

Could be something as simple as the
foundry's date code. February '63?
