Finally, got my 5.9 Dart to the track. It went well, then it went to hell.

I can't say enough positive things about Manton and their products. They take care of their customer and make top quality stuff. The tapered pushrods that they offer are incredible. I used a set of Manton chro-moly strait tube 3/8" ball and cup pushrods in my solid cam 340 and they made them for me on a Sunday while I waited and told me that they don't care how I break em (as in, with a hammer and an anvil!!! literally!!!), if they break, they will replace them! That's good stuff and good business! They were a bargain price too, at about $100 and change! This was back in 91 and I still have and use those pushrods. I have hammered a few of them THROUGH the lifter cup....minor "swaging" effect on the ball end....NO functional damage! They are tough and I still use em!
