Using the stock engine with its factory compression ratio, means compression probably down in the high 7s, so you want a camshaft with a tight lobe separation to get cylinder pressure up. You also don't want "too much" duration at .050" because again, that can lower cylinder pressure. Lastly, that Oregon grind I posted will have a noticeable idle because of the wide duration split and the narrow LSA, similar to the Whiplash and Thumpr style cams. It'll also pull strong. Whatever you choose, good luck with it!
