Yes. Hydraulic flat tappet and stock adjustable rockers in a 273. I had read so many post here where people had WAY overthunk this mod. So many insisted that custom pushrods were the ONLY way possible. Instead of starting yet another thread on the subject I commented on several threads hoping for some Real World part numbers that didn't involve special measuring tools and multiple phone calls to vendor tech help centers. Found that Summit Racing has a "House Brand" pushrod that many feel is Close Enough and several vendors make a 340 Six Pack pushrod that is a Direct Replacement for what I want. Going to order a set of Melling MPR157 pushrods and do it that way. Thanks for your offer though.
