4.6l rebuild. Keeping stock crank but which rods & pistons?

I'm looking to add turbo in the future to make around 420 hp max. I hear the stock crank is capable of 500hp and keeping that.

Two Questions:
1)Should I go with forged pistons and forged rods or go with OEM stuff?

2)And what Cam (brand & specs) is good for turbo set up?

My set up will be NPI block, PI heads port & polish, cams and future single turbo.

You definitely have to go forged. Manley makes good forged rods and pistons plus they are used on the 03-04 Cobras. You are gonna want your compression to be anywhere from around 8:7-9:1. Check out MMR they have pretty good selection of forged internals. Just tell them what you want and they will tell you what will work for you.

Actually if you are only gonna want to make that much power OEM will be fine, but for peace of mind, and you will probably want to get more power (trust me you will get the bug) I would definitely go forged

I would go forged.

One thing to keep in mind, which I say this to anyone who is looking to build an engine, do a cost comparison before buying parts. With using you current block, it will need (at the least, in my opinion) to be machined, hot-tanked, re-bored, re-honed, new oil pump, freeze plugs, etc... plus your stock crank will need to be re-ground and re-balanced with your newly bought rods/pistons. Adding up all that, it might be worth while to just buy a new short-block ready for your heads/intake/turbo and dropped in your car. MMR and I'm sure some other reputable builders have short blocks built to handle the power you are looking for for about the same amount of money as what it will cost to do the above (and without the hassle and inevitable headaches that come with piecing together an engine)....just something to think about...

As far as cams go, why not do it right and get custom ground turbo cams...?
