My Harland Sharps arrived today. We’ll see how they work out. I haven’t weighed one yet however they seem heavier than they use to. These are the later ones that have some geometry changes to help complement the aftermarket heads. Intakes and exhaust are a little different.

So there is a reason why they make different levels of lifters, kinda like why they make different levels of crank shafts. If your building a 500 HP style engine do you need a Sonny Bryant Crank, top dollar bullet proof rods, Steel shaft rockers, etc. probably not. If you have a mild cam and correct Valve spring pressure and correct geometry, you don.t Need super strong expensive rockers. Rocker arms seem to take the beating if other components in the valve train are not correctly matched, too much spring pressure lifter float etc. the rocker being the fulcrum point gets constantly slammed. Now if you are building a High HP high RPM engine with a radical cam, then absolutely go with steel Rocker arms. My point is that each build can require specific components, and not all need the top shelf parts. can get very expensive very quickly

Yeah kinda like we all know all the top shelf good guy parts are and I can build a heck of an engine with all but then I wake up and come to my own reality. Everything and anything can and will brake under the right (wrong) circumstances. To be honest I had to call back after I ordered the rockers to ask what the price was. Couldn’t believe I forgot to ask but I did. Not as pricey as the steel crowers but a little higher than most others. I was going for the best fitment and bang for the buck as well as the best customer service. Not being able to confirm part number for my app and the unknown delivery date shaft rockers became out of the question this go around. I don’t know if any other rocker arm manufacturer that has worked with aftermarket head companies etc to manufacture a better fitting rocker. Not implying their the best by any means but their here and awaiting install as manufacturing and delivery are huge issue with many parts. Like smitty and others have said don’t wait on anything you think you might need. Get it or order it now. Problem with paying and ordering is there’s rarely a certain timeframe on delivery. I’ve been hearing a lot of 4 to 6 months but could be longer. Sucks
