SBC swap into 1983 Cutlass with 307 & 2004R

[jpoole]

Hi all, new to the forum, well been lurking a couple of weeks. I am looking to replace a tired 307 Olds with a SBC 383 stroker in my 83 Cutlass. I have found stuff about V6 swaps etc but would like to get a parts list going for what I need for my build. i have a few requirements to follow as I get get tested for emmissions equipment being in place, not tailpipe sniffer. Looking to keep:

1. AC
2. Cruise Controll
3. Catalytic Converter
4. CCC system (replacement chip for no AIR and modding carb to open fully)
5. Gauges

Want to install ZZ383 motor and serpintine belt drive system and keep my 2004R as I want to keep my console shifter.

Questions are about parts needed to swap, do i need electric fans, send any tips or tricks and will my stock shifter work with a 4L60E? Can I elimate the EGR system with the proper chip?

Thanks!

Since I don't know where you live I can't comment on the legalities of the swap. If I understand correctly from your post they don't actually test for emissions, just a visual inspection that the emissions equipment is in place? If that's the case you need everything the car came with after your SBC swap. The charcoal canister will be there already. The cat is no problem. You'll need an intake manifold that has a provision for EGR. You may need an AIR pump and exhaust manifolds with tubes if the 307 had that.
All of the peripheral parts including motor mounts and serpentine system should be able to be sourced from a later Monte Carlo. You can also use the fan and shroud from it. Keep all the sending units from the 307 and your gauges will be unaffected. The complicated part will be properly calibrating a CCC carb. I can't give you any pointers on that but I'm sure someone else can.
This isn't necessarily a complicated swap but, honestly, it could nickle and dime you to death rounding up all the parts. Your best bet is to locate a mid-80s Monte Carlo donor and get everything you can. There is a LOT to change to do a proper Olds --> Chevy swap that appears factory stock. There are several items that need to go left to right and right to left. A larger Olds engine would be a direct bolt-in and save a ton of time, trouble and money.

I swapped out A Buick V6 in my Regal for a complete MCSS powertrain. Not much from the SBO will swap over to the SBC. You will need a Chevy CCC Qjet, a L69 305 Qjet would be best. Chevy and Olds Qjets are setup very differently, inside and out. A Monte Carlo V8 CCC computer harness and ECM, a SS one would be best since the SS ECM has the better HO PROM chip. You can also get a ZZ4 chip. The V6 computer harness was set up very different from the 305 computer harness with my swap, I am sure a Olds 307 computer harness is setup different too. However it is very easy to swap computer harness in these cars, just unhook 3 plugs inside the car, remove two screws, and the computer harness pulls right out.I had to modify the original V6 gauge/power harness for the V8 since some of the wires were too short to reach some of the senders and choke. Probably best to get a Monte Carlo V8 gauge/power harness for the engine, but since it is simple you could probably reuse your original harness like I did. Of course you will need to swap out the Olds motor mounts for SBC mounts. You will probably need a junked SBC Monte Carlo or F body as a parts donor, or buy a complete drivetrain from one of those cars to pick for parts.
