I am going to be doing a 355 rebuild on my LT1.

what is the best rebuild kit to get and where from and how much is it? i want forged.

What size injectors for 500+hp?

I will be getting the Advanced Induction Full Port heads/intake/cam combo.

I want to be able to add a turbo in the future. so i need it to be able to handle it.

Also, what is the MSD 6AL ignition all about and how does it work? and do i need it?

Thanks in Advance
