I figured it would be nice to have a thread where a guy can find all the part #s and what works. Feel free to pitch in if you guys have some stuff to add.

Coolant Temp Sender (98 Camaro 3-wire) 12551708 or TX111
(I don't have the part # for the pigtail, but they're quite common in '99-up cars+ trucks. My Ebay item # was 120777784118)
(I also don't have any part #s for the oil pressure adapter)

B&M TC lockup controller 70244

If you use the Hooker cast LS1 exhaust manifolds you can use steel 2.5" flanges- Patriot H7265 $10.95 w/gaskets! I think you might be able to use these flanges on a set of Ls1 Camaro exhaust manifolds too... (?)

TCI flywheel Speedway item # 282399753 ( the price on this keeps going up and up)

Lokar dipstick Speeday item# 4915008

A/C compressor and alternator: I used a 1991 Camaro 5.7 compressor and a 1996 Chevy 5.7 truck alternator (alt fits LS bracket)

More to come

YOUR RESULTS MAY VARY! These are my part numbers for LS truck motor to G body:


Cheap headers that worked for me (pass side needed hammering) Pacesetter 702256

Dual Plane intake and MSD combo kit Edelbrock 7118

Smaller P/S pulley to clear steering box Dorman 300-201

Crank spacer for curved flexplates GM 12563532

LS1 motor mounts: 1” setback – will need new holes drilled in K member Trans Dapt 4516

165 deg thermostat SLE 100223

There is a perfect “U” hose for the water pump - if you want to bypass the heater Dayco # 87629 or Kelly-Springfield #S-4354

All you rich guys disregard this:

When I am looking to buy, I Google the part number and then hit the "shopping" button, then the "sort by price" button. Some of the smaller speed shops have HUGE markup.

I don't think there a whole lot of those around here! Maybe retards like me who buy crap and then find out I could have done it much cheaper if I was paying attention! :roll:

Pacesetter headers DO NOT work with the BRP mounts. I beleive the only headers that will bolt in are the BRP's.

Northern radiator makes a cheap alternative radiator vs the Be Cool and other high price brands for same side inlet/outlet aluminum radiators

A couple combinations that work

BRP engine mounts
Iceman 4L60E crossmember
BRP headers
Musclecar pan/Holley pan

Setback mounts
Iceman crossmember
F-body Pacesetter headers
CTS-V/narrowed F-body/truck

If you need to use the dished flexplate for your LS swap and are using a 4L60E, don't bother with a GM flexplate

A good mod is an oil catch can instead of the crappy PCV these engines had. Regardless of what is done or what you are planning to do it's a mod worth it's weight in oil :lol:

Intake couplers and pipes from here
www.intakehoses.com

Airaid makes an awesome product for people like us custom engine swappers with this "universal" intake tube. Really nice piece actually
http://www.ebay.com/sch/i.html?_trksid= ... d&_sacat=0

For anyone in the process of their build and planning on going to a FAST intake in the future, upgrade your MAF now and save money later. Here's two things you can buy to make yourself a 100mm fast for half what others charge for pre-made ones. Just convert your 3/5 wire to the LS7 schematic and get your car retuned and your good. The MAF is cheaper at a dealership I just wanted to put a link up

http://www.ebay.com/itm/LS7-LS3-Corvett ... 5f&vxp=mtr

Ill just keep adding more I'm bored and still waiting for my trans and converter to return

You'll have to track down each person's build thread and follow along. I think the EFI guys are using a speed-density tune and either running a 700r4 with a cable to the speedo, or 4l60e with aftermarket gauges. I'm not real sure on that though. I did a carb on mine this time.

Where'd u find a LS6? They're kinda hard to come by
