they also show stepped headers available in their long tube's with primaries up to 2".

Re: LS engine swap info
 

Those appear to be the same ones from BRP, coated is $499 from BRP. PN45666 is the coated version of the 45660.

Re: LS engine swap info
 

Sorry if this has been answered, I've searched and searched and have gone through a lot of threads.

If I am using the under hood fuse block that came with the 5.3 in my swap, do I run the grey wire from C3-F1 (fuel pump power) straight to my fuel pump of does it need to go to a relay first? I think it already goes through a relay on the block but I'm not 100%.

Thanks to everyone for all the info that is out there.

Re: LS engine swap info
 

look at this schematic on this page:
http://lt1swap.com/pictures/fig_7.gif

It appears that the gray (18ga) wire (circuit 120) from the fuse block (location F1/ connector C3) goes thru the relay on the fuse block and go straight to the pump.

here is the connector ref that I used to ID the wire:

Hope this helps you out...

Re: LS engine swap info
 

Confirmed what I was thinking. Thank you

Re: LS engine swap info
 

The TRailblazer SS exhaust manifolds are available from GM Parts direct. On the homepage, put 2005 Trailblazer and click the model option with the 5.3 engine. The left side is $51.94 and the right side is $49.21. I will order a set for my next build in a couple weeks. These are suppose to tuck inside the 67-72 frame rails.

here is da link: http://www.gmpartsdirect.com/catalog/frameset.cfm

Re: LS engine swap info
 

those for the 5.3L on the V8 TrailBlazer... are the same as the ones on the 6.0 LS2 TrailBlazer SS?

Also, TBSS's were made from 2006-2009.

Re: LS engine swap info
 

I just changed the search parameters for 2007 Trailblazer SS with the 6.0 and the price is the same, so I ASSume its the same manifold. They dont list a part number on the website. I just added both to the shopping cart and the total with shipping is $126.22 for the pair

So how bad would it drive with on tune...

Re: LS engine swap info
 

Back on Post #8, the link to Do's Blocks no longer works since that company is no longer in business. I was searching for the Denso 10S17F 10S20F Suction and Discharge Compressor Adapters for the truck compresser in the OE truck position. The old part numbers where AA2209 and AA2210.

Those numbers lead me to coldhose.com and these parts:

http://coldhose.com/catalog/product/...g/category/39/

Those are not what I was looking for but will certainly work.

I did find on their site these parts, which are the ones I was looking for:
http://coldhose.com/catalog/product/...s/category/39/

So, for anyone looking for the adapter fittings, there is the info for two different styles that are currently available and a source to get them from.

Hope this helps some one.

Re: LS engine swap info
 

So, if a guy bought a wrecked 2010 Camaro Ss, with a complete, running engine with all wiring, how hard would it be to transplant it to a '69 Chevy C10?

Re: LS engine swap info
 

This depends on how you want to do the swap, i.e. how much do you want to spend? or what is your skill level with wiring?
You can buy a plug and play harness/pcm that all you have to do is connect like 4 wires or you can completely rework the stock harness and have the pcm reflashed.
It's not hard but it does take some time and a whole lot of patients.
Brendon at lt1swap.com can reprogram your pcm and he has some info about the harness : HERE

Re: LS engine swap info
 

I just helped a guy do this very engine in a 72 GMC. You will need a different oil pan, have to remove the oil cooler from the side of the engine and if its an L99/6l80e, you will need a high hump floor to clear the trans.

Re: LS engine swap info
 

I did it here: http://67-72chevytrucks.com/vboard/s...358692&page=17

Re: LS engine swap info
 

Looking for any and all good info on ls swaps. I have a 68 short bed I'm putting a 5.3 4l60e in. Any help is appreciated.

Re: LS engine swap info
 

Has Anyone Used These..... http://www.jegs.com/i/Hooker+Headers...FY-Cfgod7bYM3Q .Any Thoughts??

Re: LS engine swap info
 

The Hooker header looks good, but being cheap, I found a set of Trailblazer SS manifolds on eBay. I took off the heat guards, ground off the mounting points for them, plus all the casting flash and part numbers. They look awesome and I have 40ish dollars in them. Just talked to a guy about ceramic coating them and they'll be done, still at half the cost .

Re: LS engine swap info
 

Those are basically 2010+ Camaro manifolds... If you're luck you can come up with some 2014+ Z28 stainless steel manifolds off ebay... for the cool factor... ;)

Re: LS engine swap info
 

I used them on the '67 Panel Truck. They fit like a glove and were easy to connect the rest of the exhaust to. The shop that did my exhaust just welded the o2 bungs in the pipe below the manifolds. That is a good price. The cheapest I could find on e-Bay when I bought mine was $319..... I couldn't find any GM takeoffs at that time.

Re: LS engine swap info
 

Hi, do u know of any resonable price long tube headers that will fit im swaping a 5.3 in my 67 c10, thanks a lot!

Re: LS engine swap info
 

I'm not sure what you consider reasonable, but a lot of guys are running the Doug Thorley 324y-c https://www.summitracing.com/parts/dte-324y-c
I have them going into my 71 with 6.0 and they seem to be a really nice fit. I've had them in once with the engine in and out several times.

Re: LS engine swap info
 

They are nice i had done of his headers in my 71 impala, great quality!

Re: LS engine swap info
 

A lot of good information in this thread!

Re: LS engine swap info
 

I will definitely be referring to this thread a lot for when I start my swap this spring. 2000 lq4 4l80e in to a 88 3500 crew cab.
