Does anyone know the largest cam I could put in a stock '87 351W without cutting the pistons? That's the one I have in mine, but can't find the specs. I need duration (in/ex) and lift (int/ex). Concerning lift, tech guy at FRPP suggested 472/496. I need to get the book (going to the Ford dealer now to get one).

I'm looking at some AFR 185s for the 351W and they can't tell me if the pistons need to be cut or not. I already know the answer for the 302 with stock cam. I need the answer for the 351. I'm thinking they won't need to be cut (I'd check of course anyway if I did buy the heads, but of course I'd like to at least have a clue b4 I do) since the 351 pistons already have eyebrows.
