Re: 69 LS3 Swap

About to start this as well with an LS3 in my 67. Can you give us a little run down of what you are running for swap parts. Mounts. Headers. Accessory drive etc. Just curious as I am about to pull the trigger on a bunch of holley stuff

Re: 69 LS3 Swap

Wish you luck in your swap, there are a few of us that have done it so we can help you at any point.

Hey John, after seeing this video I don't think LT swaps are going to be sooner rather than later. Holley has a solution for the accessories now.

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.

Re: 69 LS3 Swap

More tear down last night. Subframe is ready to come out.





A quick question for those of you that have pulled a subframe out before. I was thinking of just putting a 2x10 under my jack stands and setting it up against the floor. I think that will be fine. Thoughts?

Cool Re: 69 LS3 Swap

I used the Dakota Digital VHX gauges in my swap. The Vhx with their OBD2 BIM makes a great plug and play combo. It takes most of the readings directly off of the PCM. Great looking gauges with a modern yet retro look.

Re: 69 LS3 Swap

I really do like the Dakota Digital gauges and it would solve several problems I would have. My bigger issue would be that I dumped about $550 into stock console gauges and a tach a few years ago. I suppose I could just sell those and recoup some of my money.

The way I understand it you just hook up that OBD2 BIM to your OBD2 port and to the Dakota Digital control module and that is basically it other than power, switched power and ground I assume?


On the VHX models can you access any of the other info that may be in your PCM like trans temp, intake temp etc?
