Smog pump delete questions

[Pegasus]

Hey gang,
I have a 266 V8 that I am working on and have a question about the smog / emissions system. First let me say the engine runs great, nice idle, plenty of power etc.
My question is about removing the smog system. Will this affect the way the truck runs? As you can see from the pics, the pump is plumbed through a valve that diverts into the block via the injection rails. The only other connection is a small vacuum line to the carb. I don't want to hurt the performance of the engine so I'm cool with leaving it in place. Just trying to de-clutter the engine bay and also don't want to be "hunting" for parts down the road when the pump and valve wear out. If it is cool to remove it all, do I just cap the carb vacuum input and plug off the holes where the air injection enters the block? Thanks so much guys.

Wow, nice looking motor. Most 266s are caked in decades of oil-grout...
You can remove all of the parts. The plugs for the heads are a little tricky to source. They aren't normal pipe plugs. If you do a thread search, it might come up. IF not Google it. Somehow Google searches the forum much better...?
The vacuum line can be capped at the carb with a normal rubber cap.
As far as performance goes. you shouldn't notice any difference. And don't scrap any of the parts. They are worth something to somebody. I might even be interested, but they are a bit old for my application. Assuming you live in a state where these emissions laws don't apply?

Hey DealBreaker, I wish I could take credit for the condition of the motor, but the PO took pretty good care of it. Most of the work on this one is going to be in the body. I am in a rural area down south so inspection is just the safety stuff, nothing up the tailpipe. I'm still on the fence about removing it. I kinda like the way it looks. I'm sure that sounds weird. Just don't want the system to fail and the truck start running like crap.
Thanks for the info though.

Thanks Zaedster. That looks like what I need.

Hey Zaedster. Do these plugs require the use of the rail tube spacers or do they just get pulled also?

Negative on the tube spacers, all smog items and spacers are omitted from the engine. Just install the plugs and go.

Hey Z, Just placed my order for the plugs. Do you recommend any type of sealer on the threads? Maybe some high temp like ultra copper? Thoughts? Thanx...

Yeah you can put a little anti-seize on the threads, just snug the plugs. Don't torque them to a crazy value.
