Re: Successful LS6 Intake Manifold Swap, DOD Retained
I basically cut the end of the connector off (kind of in half), which leaves you with metal leads encased in plastic. I left material on both ends of the connector so I could work with the connector end and the VLOM end. With some careful saw work and some melting, I exposed the metal enough to get a good contacts on both ends. I then soldered wires to the little metal leads that I had exposed, which electrically reformed the connector. I then used epoxy to protect my solder joints on both ends. If you need more detail or a better explanation let me know and I'll try to get back to you sooner.

There's a great advanced LS tuning done by him years ago as well. Really good read

Re: *HOW TO* LS6 Intake Manifold Swap
LS6 Rectangle port manifold to LS4 cathedral port head. Is that not important?
Re: *HOW TO* LS6 Intake Manifold Swap
yes that would cause problems. Are you sure its an ls6 Intake?
Re: *HOW TO* LS6 Intake Manifold Swap
^^^yeah it sure is. Part #12573572 stamped on it indicates LS6. Hmm.
Re: *HOW TO* LS6 Intake Manifold Swap
Ohkay nvm. I stumbled upon an answer on LS1Tech. Here it is in case anyone else has the same concern:
ScottyBG*, 12-17-2016 09:19 AM
"If you look at the head, the pointy area at the top of the port lines up with the injector. Originally the LS cathedral head got the cathedral shape to allow the fuel injection to shoot fuel into the inflowing air stream more efficiently. Old school it was all designed around carburation, and airflow (air with evaporated fuel in it) as the only consideration. If you consider the head, without the "gable peak" on the port for the injector to shoot fuel in, the rectangular area of the head and the intake match quite well. So the addition of fuel injection, as a new technology, changed the way of thinking regarding matching head and intake ports. On a BBC the cross sectional area of a rectangular port is considerably different, than an oval port, and flow very different. The ports in your LS6 manifold flow appropriate amounts of air for the ports in your LS6 head.
You still don't want to try and put an LS3 or LS7 intake on a cathedral port head, that truly is a mismatch, because the volume of the ports are so different..."
I honestly did not know this.
Re: *HOW TO* LS6 Intake Manifold Swap
Ls6 has never been a rectangle port. Your fine to run it.
Re: *HOW TO* LS6 Intake Manifold Swap
Doing this swap and can't find a TB adapter to make it all work? Try LS Throttle Body Adapter / 3 Bolt Intake to 4 Bolt TB You'll end up with the adapter and a spacer. These only work with larger TB's like an LS3 TB. For a total just shy of $60, pricey but ya can't be picky when there isnt anything else on the market.
