I'm not trying to sell you one way or the other but I think it's a good decision to build the truck with future maintenance and repairs in mind.

I think the painless wiring harness is a little north of $1,000 without the pcm
Holy mackeral! That's crazy!! I've done plenty of harnesses over the years. I can't believe people pay that much. Maybe I should retire from running the fleet and start selling harnesses.

The Vortec heads flow well. The LT4 HOT cam is one option. Combine it with 1.6 rockers and you could end up near 400 hp with minimal additional work.

If that seems interesting then there are other options for springs.
