Hey new to the g body just bought a 83 cutlass supreme small block 400 th350 I just had a few questions maybe somebody could answer I've got plans to do either a 5.3 or 4.8 iron block vortec motor into my cutlass I plan on doing a carb setup and on a single turbo I still want to use the th350 transmission I know the transmission will bolt up to the motor but will I need a new driveshaft? And will the crossmember that's on the transmission now still work with the swap and I was also wondering what oil pan I would need to get. And last thing would anybody know what size slicks would work on the stock 14" rims on the cutlass. Any input would be much appreciated thank you!!

You need 1" setback adapter plates that bolt to the engine, and either a caddy CTSV or muscle car swap oil pan. The 1" setbacks places the engine in the g-body factory location, so stock crossmember and propeller shaft will still work without mods.
