Swapping motor out

[ryanstrucking]

Ok, here I go again.
I'm swapping out my 350 TBI for a 454 TBI
I have a 87 K5 Blazer with 60/70 diffs 350/ 700/203/205 doubler and 44 swampers.
I was wondering if the harness from my doner truck a 87 2wd harness will plug into my fuse block without any issues as I sold mine with my motor
Also I was wondering what is a good set of headers to run with the 454 and or what have you all been running for exhaust?
Here are a couple pics of how the truck is sitting now.
You may notice my front diff is tore apart as well.....
replaced the o-rings in my ARB, swapping out the axles (going to Yukons inner/outer and 300m u-joints). I also removed my cross over as I'm going to be installing a full hydro steering set-up. I will add more pics of that as I progress.
thanks in advance for the replys/ feedback and flaming

did you get the axles and such from NWF or just the slugs?

I bought my drive flanges from NWF, Bought my axles off a local 4x4 shop (they matched a price that a vendor on the Pirate board was selling them for.

I'm also picking up my high steer arms from NWF, they are a really nice arm and the price is reasonable.

good luck with the build, it is a sweet truck. As for the engine and harness question i would post up in the garage, more people will most likely view it and reply to it more.
