The G-Body Swap Thread
i would like to do a mild cam and some head work to mine but they do emissions testing every time your tags expire in delaware so i would go through frequently...i need to post some pictures of my swap in my 85ss el camino since its almost done, i made all my mounts from scratch and used a 6.0 with ls1 intake and ctsv serpentine.
i also have to get my ride smogged every two years or until collector plates are reinstated.. I first need to take it to the referee to get the approval sticker then the smog station.. I plan on doing mild upgrades as well..
oh btw pics are always nice.

I have finished the "bible" as someone posted.
Unless I missed it...(took 3 days to read it), I never saw an answer to these. I saw people ask, I saw people reply but none confimred.
I am going with a LS1 drop out from a 1998 Z-28.
1) What engine mounts? I want A/C I dont want to mod the case or box. AND id like to leave the a/c compressor on it low.
2) Will the stock manifolds fit? I am not running cats!
3) I am buying a CTS-V oil pan, it will clear yes?
I am also, building a list of step by step for this swap. This way there would be another great thread with pictures!

2. My stock ls1 manifolds clear good. haven't tried the trans linkage yet though.. as for the cats i have to run them, decided to use stock cats for now... If you don't need them then you should be good.
3. CTS-V oil pan fits great with those mounts!! BUT your a/c & alt won't... I used speedway motors high mount alt kit. There are a myriad of different routes to go. The kWiK performance brackets are a good option. Also i had coil interference with my non a/c heater case not sure if the a/c version does too though. I tried my block off plate and it had a PLENTY of clearance! We just notched the box for clearance...don't know if the BRP mounts work with the pan i would believe so..
plenty of pics on my Photobucket account..

I did read in this post that there are guys with the stock Zero offset and fitting the a/c and alternator.
yeah i thought about them AFTER i picked up the 4595 plates... Seemed like everybody did the 1in setback....I would think if i went with the truck or Vette accessories then i wouldn't have this issue.. I do believe that if i used the stock location plates then the CTS-V oil pan would be really close to the engine crossmember... With the 1in setback plates the oil pan clearance is great!! I bought my 99 Trans Am complete and wanted to make the best of it..

Any advise on which and quality / cost?
Also, mine will be return-less fuel system. How much an line will I need to go from the tank to the engine?
I will say the transdapt 4595 plates and mounts are sorry... I used just the plates with my factory clamshells and frame mounts. Buy just the plates and mod them if necessary. As for the fuel line i have emissions to go through so that's a whole different story.. I am hoping to use a racetronix pump with a Corvette regulator. If it works then i will switch my fuel rail from drivers side to passenger side.. The Evap portion still has me puzzled...
For those that may be wondering what the pacesetter fbody headers look like on the engine. Will probably have pics of what they look like in the car this weekend maybe.
The kick out/flare out etc of the driver side. Depending on all the shifter linkage clearance I may heat this up and attempt to bend them inwards a little.

I gotta bend the headers too. Gave it a brief try one night, didn't have a long enough leverage arm so we quit trying. Haven't tried since. Definitely let us know how your progress goes.
I think I want to run new hard stainless line, should I go with 3/8in hard line or 1/2in?
I want to braze fittings on the each end to run -8an I think from hard line to the rails. And -8an from rear of the hard line to the filter/regulator then -8an from feed of the tank to regulator and -6an from return of the tank to the return side of the regulator.

i searched this thread but couldnt really find what i was looking for so ill post a question here:
for you guys running a/c in you g-body, im looking to use the factory G-body HVAC system and either merge it with the f-body condenser/compressor or maybe the smaller sanden 508(mounted in the f-body bracket down low). has anyone done a similar setup or what did you use if you chose a different route?

Been wondering a little about A/C as well. I know a frame notch is pretty much necessary if you use adapter plates. And BRP I think no notching is needed.
I wonder how a custom bracket would do to push a Sanden compressor out further to line up with rest of the pulley's??
Like this
Or
With the factory truck bracket and compressor maybe even the car compressor & bracket, I think the end of the compressor/bracket hits the mounts with 1in setback plates (for those using that setup)
I would think a custom bracket like above but push it more forward so it's no longer running on its own belt if you use a new Sanden Compressor.

i have the BRP mount kit - which is supposed to allow use of the a/c compressor in the factory LSx location... but guess what? it doesnt fit (atleast not with the lines bolted to the back of the F-body compressor). im gonna give them a call today and see what they say.
For AC I am going to make a bracket similar to the KWIK setup to mount a Sanden compressor high on the passenger side. I have also seen one on the net that mounts in the same location but uses the compressor similar to the stock Monte SS.
