Carb'd LM7 into 1994 OBS swap questions

Hey everyone,
I have been moochin off of all your build threads for awhile. I have found alot of info to help me with my build. I have ordered alot of stuff and am getting ready to start my OFFICIAL BUILD THREAD, hell yes. I am very excited. Anyway, before I do that I have a few more items to buy but need some help making sure I get the right parts.

This is going to be a LM7 swap into a 1994 OBS with a carb conversion, and retaining my 1994 NON-PWM 4L60E.

Here is what I have now:
Edelbrock Performer RPM Carb'd LS1 Intake manifold
Holley 750cfm double pumper carb
MSD 6LS ignition
Dirty Dingo engine mounts
LT Headers 2" primary's baby (thanks to DBRODS)
(2) SLP Loudmouth mufflers
GM flywheel adapter with longer bolts to use my early 4L60E, thats right a carb with a 4L60E.
Transgo HD2 Shift Kit and Corvette servo

Here is what I need help with:
Will these work the LM7
Oil pressure adaptor: http://www.summitracing.com/parts/ATM-2268/
Temp sensor adaptor: http://www.summitracing.com/parts/ATM-2277/

Also, on the TBI engines like mine does it have a factory return fuel line or no. I plan on using a fuel pressure regulator at around 7 PSI with the factory fuel pump and instead of dead heading the fuel pump and ruining it, I will put in a return line.

I am not going with A/C for now so what do I do with the two heater lines that are off of the LM7 water pump?

I am sure I will find more questions, I am probably picking up the LM7 this friday. Thanks for all the help, this site rocks!

Should be a nice swap. You are going to save yourself tons of wiring headaches going carb

That is the plan. It will be a good setup and save me some money as long as I don't have trouble getting my ECU to continue to control the trans. Was going to buy a Thumpr cam but getting low on funds at the time. Should have this thing done for around $2,500.

not to sure how it works on the 94 but i know for mine i would have to buy an aftermarket tps to put on the carb

Your truck has a factory return line.That temp sensor adapter won't work with the stock sensor.There is pictures of the adapters on this page http://www.ls1truck.com/forums/lsx-t...ed-swap-3.html

Is there any way to make those adapters from fittings at a hardware store or are they special pieces?

Also, what do the 5.3's with the stock cam pull in vacuum, I need to order my rebuild kit and power valve for the carb and need some numbers.

I looked everywhere and couldn't find those adapters anywhere except the ones in the picture.If you find them anywhere please let me know.
