If anyone is looking it up, I'll save you the trouble. That is a Comp Magnum solid.... .468" lift, 270 advertised, .022" lash.
20-246-4 - Magnum™ Mechanical Flat Tappet Camshafts

Thanks man, I noticed other people like them and if I upgrade the engine it might swap over too. Is it only compatible with LA 273 and 318?

edit: jegs was saying 318 but summit is saying it'll work on 360's
