I would like some info on boxed rods. Did they fill up beam with welding rod ? Or cut a pice of steel to fit and weld it in. Must have been real heavy. Hard to imagine something like that nowadays. Picks would be cool.
Cut a piece of flat steel and welded it in. I have also seen some that had a rod welded in the center of the I-beam from the big end to the small end, I would think that that did very little other than add weight.
All I know is that they were boxed like a frame to strengthen them. Primitive by today's standards however they were experimenting and leading the charge to go faster..
That's all there was till Fred Carrilo came along with his H beam machined rod, Freds rods were a work of art !!! Used them for years and always spot on the money DND
i suppose you would have to straighten and resize both ends , and then add some weight to the crankshaft to balance it?
In 1961 I worked in a speed shop and we were bending rods in our Hemi dragster. The owner tried a set of Aluminum rods but they only lasted a few runs before stretching so he had a welder TIG boxing plates on some used stock rods and had it balanced. That engine lasted most of the season. Price wise the stuff from Callies, Eagle and others are a bargain today.
I have seen that too! Heres a pic of a rod with a piece of square rod welded in the center of the beam. The actual boxed rods were supposedly pretty strong, but heavy. I will try to find a pic.
