Be carefull with those Crane Retrofit Hydraulic cams in a LA small block. The base circle was too big for me and exposed the lifter's oil groove at max lift. Another guy over on moparts had the same problem so it just wasn't my engine. I have a '71 340 block and he had a '73 340 block. You might be fine with the 360 block but look it over closely if you go that route.

The other guy I am talking about, he didn't check his during assembly and he had a lot of valve tapping and very poor oil pressure. And this was on a 416 that was running fine with a flat tappet; he only changed the cam.
