Craigslist sanity check: 4L80e + 5.7L SBC 350

The purpose of the carb was more for removing the complexity of the system for me as a garage mechanic.

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.

Wow, that is neat to know that I could get there. The article wasn't as detailed as I would need to even attempt such a thing though. They talk a little about the one piece main seal needing modification and some machining of the spring mounts. All a little out of my tool and knowledge range. I'm happy for now just knowing that down the road I can give it a shot or have someone do it when the truck budget is replenished For now, I think I'll notice enough of a difference over the v6 4.3L currently in the truck.
