408 Questions
Im going to be starting a 408 Stroker build soon and had a couple questions before I get too far into it, I'm going to be boring a lq4 block .030 over & I know the main things, what crank, pistons, and rods I need along with heads an all but what I don't know is:
1. All my accessories from my 5.3 should work for the front of 408 (lq4) block correct?
2. & will my 5.3 wiring harness hook up to the 408 and everything work without needing any additional wiring? Just didn't know if I would need a new wiring harness or not
- Thanks.

FYI your power is in the heads and cam, so a big cube motor will require big heads to support it otherwise you have a big cube motor that makes same or less then some smaller cube motors make cause heads and cam sizing was off

I am starting a NA 408 as well, I have 317s for it but I am probably going to upgrade to some LS3s/L92 heads. I just need to figure out what the best route is for the intake. I will either spray or go turbo in the future so trying to figure out what CR I want to go with.

I think I am shooting for around 10.5, going with 68.5cc heads a thin head gasket and a 10cc dish, then if I decide to go boost I can get the heads milled and up the chamber to 72 cc and go with a thicker gasket and get down around 9.5 staying with the same pistons.
