Check this out. I bought 3 supposedly nos pushrods a couple of years ago from a seller in ebay. Been tuning the carb on my Super Bee this summer. Been hammering on it quite a bit while doing this, if that really matters. Down to wot throttle and the last time out it felt like it was running out of gas. Pulled it apart to check and clean the filter. Luckily I decided to pull the pump and check the rod. Wore .305" in about 700 miles.
