I'm looking into getting roller rockers for a 410 stroker I'm building, I really want Harland Shaps but can't swing the $700 right now. I found what I think is a good deal on a set of Speedmasters, but it's the first time I've heard of them so I don't know if I should pull the trigger or save the $$$ for a set of Harland Sharps. Another question I have is will I need new push rods with them. I'm on a tight budget and the original plan was to reuse the stock stamped rockers and push rods. I have a .508/ 292 purpleshaft for it already and it's just a street/strip deal. Any advice is greatly appreciated!
