I Recently Purchased a 454 big block with motor. I was wondering where can I find the wiring and all that stuff for a 454. Because I can’t be using the same wiring from a 350 5.7.

For the wiring, we mostly use AllData. That's an online service manual site that independent shops pay around $1000.00 per year for access. You can buy a subscription for just your truck for around $27.00 for a year, and as I recall, about $47.00 for five years.

If you're going to be working on the engine, here's a dandy series of videos you might find interesting:

This is the first of 17 videos for this engine build.
