I really think this subforum could use a sticky of parts that work for an LS swap, it would give a nice place to quickly see if a part has been tested in a 3rd gen LS swap, but it needs details, one thread that does a great job with details is this one

https://www.thirdgen.org/forums/ltx-...ls-engine.html

it gives a breakdown of each oil pan, and how it does or does not fit. but the oil pan is only part of the equation, intake manifolds, FEAD's, exhaust parts, ect, could all be mapped out this way.

I see parts fitting into 3 groups

Just plain fits and works
-as implied, the part bolts on, no fuss, and works


works or fits conditionally
-this part can work, but there are attributes about it that make it less desirable, or it needs to work with other parts, this could include an oil pan that clears the K member, but hangs down low, or headers that work with a tubular K member, but not a stock K member.


doesn't work
-I use the term "doesn't" carefully, with enough hacking and welding and messing around, anything could work, but it's outside of what most would use for a swap.


I'm going to update the follow on posts as I do research, but if you have anything to add, please post up.

Please reply to this thread with your parts recommendations, and things you used or found not to work in your swap.

Hi, ericjon262. I'm glad to see your interest in these things.

There are more tech threads like the oil pan thread you found. You'll want to check this out, https://www.thirdgen.org/forums/ltx-...date-ls-5.html

The individual tech threads were created for the specific purpose of supporting a new LS Swap sticky, kind of like chapters of a book. The threads get straight to the point so people don't have to wade through hundreds or thousands of conversational posts. It takes volunteers to make this happen, and as you'll see in the link above.... I'm looking for volunteers. The sticky has not been created yet.

Volunteers don't necessarily have to be the technical experts themselves, they just need to have good writing skills and a strong ability to learn. Experts often will help fill the gaps if somebody else will take on the work of writing up the tech thread.

 

I'll dig through the info and see if I can get things condensed a little, and help make it a little easier to find.

 

That link might of been referring to me from the OP...maybe! LS3 manifolds will work/fit with some tweaking, cutting/welding.
Also using 4th gen evap/fuel/returnless lines along with the tank/sump/charcoal canister. The lines do need rerouting/cutting up front, but 95% of the routing if "correct" as is.

 

Works - Hooker turbo manifolds, crossover - works "as is" but does hang a bit low can cut the flanges off at the welds and stick new ones on and they tuck up nicely

Works - Hooker transmission crossmember without needing all the other Holley swap parts "system"

 

Good to know, been wanting to try this part, but wasnt sure it would work with my set-up.

 

It's kinda overpriced for what it is but I get where their thoughts are on it as it's more or less the last crossmember you'll have to buy as you just need adapter plates for any transmission. I ended up cutting the torque arm mount off of mine my 2 piece arm has it's own crossmember

 

I kinda want it for the TA relocation as mine is still on the tail shaft, but the price is whats kept me from buying it. I thought i read on here its not being made anymore though.

 

Summit Racing still has a whole bunch of them. But yea I know what you mean about that price

 

Yeah, not cheap. Maybe, ill look for a used one.

 

Hawks also make swap crossmembers but they don't have a TA mount on them but wouldn't be too involved to weld one on there

 

I bought one of those. Damn holes dont line up at all. I ended up modifying my stock piece, but id like something beefier.

 

Ahhh chit that's a bummer. I guess that's one nice thing about the Hooker is that it's actually lines up just right

 

Yeah, its very well made.
