Cross posting here from my old build thread. I just started tear down to do my LS3/4l70e swap. Here are a few pics.








I don’t know if anything has changed but my holley/ hookers (same brand now) had O2 bungs. Are you looking at the Holley website?? Sounds like you have been given bad info.I'm also going down the Holley/Hooker path for my conversation. Currently I'm stalled on my header purchase, was about to pull the trigger on the same set (Hooker Super Comp Headers 2276-1HKR) and learned this set does not have o2 bungs. In doing a little more research it appears Hooker's only LS swap headers with the o2 bungs are the sets that are for DSE front subframes. Welding in bungs is not that big a deal but I really don't want to screw up the factory ceramic coating. I know there are clamp on contraptions but that's not how I want to roll with my project.I put a ton of thought into exactly what I wanted to do. My brother is in the final stages of swapping and LS2 into his 68 Camaro so I have some first hand info of all the issues that arise with swapping in a used engine. I weighed that against just getting a GM Connect and Cruise engine and transmission. It will end up costing me a bit more money but I will know what I have and have a warranty so I am going with the new LS3 480 and 4l70e transmission.
Here is what I am planning on using for parts:
Engine mounts and transmission crossmember - Holley
Oil Pan Holley 302-2
Griffin CU-70009-LS Radiator and Fans
GM 19257325 Accessory Drive
Kwik A/C bracket 10143
Hooker Super Comp Headers 2276-1HKR
Tanks Inc. fuel tank and pump
Corvette regulator and filter
Vintage Air
Speedway Tubular Control arms 91036769
QA1 Coil overs
US Mags U111 18x8 (Front)
US Mags U111 18x9.5 (Rear)
I am undecided what I am going to do for a speedo etc. I really like the stock look but obviously nobody makes an electronic speedo yet that looks original. I am thinking of getting a speedo and trying to mount the factory face on it.
I am doing my best to do everything right but also not blow my budget totally out of the water. I have a pretty awesome wife and a generous budget so I don't want to ruin that.
Anyone have suggestions?
I'm just using the stock one. I did put an LED bulb in it though.Looking good Greg !!
I'll be watching
What dome light are you going to use in the headliner ??

Mine had O2 bungs in them and my brothers set did as well.I'm also going down the Holley/Hooker path for my conversation.

I did speak with Holley/Hooker support on Monday and was told that only DSE model LS Swap headers had the bung. I'll try them again to see if I get a different story. Weird...I don’t know if anything has changed but my holley/ hookers (same brand now) had O2 bungs. Are you looking at the Holley website?? Sounds like you have been given bad info.
Wow, WTH????? Check the links below.I did speak with Holley/Hooker support on Monday and was told that only DSE model LS Swap headers had the bung.

Good question, I'm hoping "Jake" in Holley/Hooker support was wrongWhy the hell would they remove the O2 bungs on an engine that requires them?
I was hoping you would chime in! Thanks Todd.Yeah, Jake would be incorrect in making that statement. All Hooker Blackheart long tube LS swap headers have O2 bungs in the collectors.
Looks amazing - I have color samples coming from TMI.... Really like seeing real exampleshttps://imgur.com/a/ird4is7
With the weather getting nicer again I am back trying to get my interior finished. Back seats and console installed.
