I finally got one.2001 LS1 and 6speed for my 73 camaro.Along with it comes the dash harness,cluster and column.Now a few questions.
First,does the 2001 have a return line or is it in the tank?Trying to decide what year tank/pump to get.
Why do people eliminate the O2 and other emissions controls out of the pcm?I am thinking it would be easier/cheaper for me to drop it in using stock pieces/pcm I have and leave it the way it was designed.How does the pcm control the fuel without the O2s?
Since I am utilizing the matching column,would it not be okay to leave the vats?
I am sure there will be more questions,but I am sure this great board will be able to help me out.
Thanks in advance,Joe

I'm working on my swap currently and I'll give you some info I've found out. ('98 LS1/T56 in '68 Chevy Stepside.) I think most people delete the emission stuff because it simplifies installation and really doesn't affect tune-ability or operation of the engine. As was already stated the front two O2 sensors are needed for mixture control.The air pump is used to heat the cats up quicker when the engine is first started and without it, the engine still goes closed loop, just not as quick. Another problem I encountered is when I trial fit the engine I had major clearance problems between the frame and A/C. The easiest fix was a setup installing a compressor pass side high but you would not be able to do this utilizing the air pump. All the aftermarket LS1 headers will have an boss for the forward O2 sensors. So why use cats, air pump, aft O2 sensors, EGR etc? I'm not bashing your idea of utilizing all the emission stuff-that is what I intended to do. But after deciding I wanted a 400HP n/a motor and started looking at cam choices and PCM programming, it just made more sense to remove from the PCM emission stuff, vats, skipped shift, etc and do the other stuff like earlier fan turn on, raised rev limiter, etc. I'm installing a Dakota Digital Dash with my swap and it has provisions for a check engine light and I didn't want any problems with false codes due to eliminators (O2, Skip shift, etc.)If it ain't in the PCM it can't throw a code. Stick with what you want, just plan everything out as best you can. Good Luck. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I forgot to add for good swap stuff get in touch with Street and Performance. They got different accessory setups in case you have clearance issues, SBC to LS1 motor mount adapters, etc. And as far as wiring harnesses and PCM programming or just info, get in touch with John at Speartech.

Have a quick question, is there a way to hook up the factory wiring harness in my swap, like how do I wire it to 12v? Or do I have to buy a painless wiring harness? <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" /> Do you have contact info for speartech? thanks

www.speartech.com/ Phone # 765 378 4908. Or another option is Dana at who can be emailed at Dana@lt1350.com www.lt1350.com/ Both these companies can modify/make harnesses tailored to individual needs, unlike the Painless Wiring setup.

If I run the 2001 fuel system,what controls the pressure?Does the filter have a regulator in it??
I thought I saw somewhere that the pcm controls pressure,any truth to this?
If I go to larger TB or modified MAF,will the pcm need to be recalibrated?
Also,I was hoping to use the cruise control,wipers,HVAC control head,headlight switch and the 2001 cluster,will I need the bcm?I know the HVAC is it's own module and think the cluster is too,but not sure.
I have ordered my helms manuals,but won't see them til next week,hopefully they will help.
Thanks to all who emailed me or posted here.

just before the filter (by the rear wheels on the F-body) there is a "T", that is the return line. there is a regulator at the end of that in the tank (to stop us from tampering w/ it). you can run a standard regulator setup w/ a single feed from the tank. 61 PSI is normal opreating pressure.
