NP, this is from his email to me. He was fantastic to deal with and I'm getting the headers today so I can post some pics if you want.

I would like to see some pictures installed. I am running a LS2 with the Porterbuilt drop member (long ways from running LOL) and most guys seem to be going with the PaceSetter 98-02 Camaro long tube headers. I dont like how the drivers side kicks out so much. I was thinking of trying the TrailBlazer SS headers but am not sure if they will work with the drop member, but I do have a TBSS so I could run them on that if they dont fit the C10, but then again I do like the look of these Doug Thorley's.

I don't think the DT's will work with the PB extreme dropmember. However, I'm 99% sure these will:

I have these headers in my son's '82 with a LS and a raised stock crossmember. Should work well with a PB crossmember too.

Hey Rob have you figured out what headers your going to run on your sons truck. I'm wondering if the Doug Thorleys would work for me with my touring dropmember. That is if I decide to change over

There are plenty around I was just offering. They dont do them any justice though. These things are high quality and absolutely beautiful.

Not quite sure yet. I know 2010+ Camaro factory manifolds will work. So those BBK's should work. I've got to put the motor back in and put the cab back on, then I will decide....

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

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.

[aggie91]

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:
http://lt1swap.com/underhoodfuseblock.htm

Hope this helps you out...

Confirmed what I was thinking. Thank you

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

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

[68GMCCustom]

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.

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...

[aggie91]

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.

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?

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

mcbassin, who sells the plug & play harness/pcm?; looking for engine for '50 model truck & am getting discouraged with info from numerous conversations regarding using LS engine/trans.
