I have a 1992 RS and am intending to swap out my L03 TB1 305 for a L31 Vortec 350. I'm planning on keeping my TBI system. I was hoping I could get some help ensuring I am ordering the right parts and if anyone has correct part #'s for the following that would be a great help.

As far as I know I need:
- Vortec 4 Barrel intake manifold
- 4 Barrel to TBI adapter plate
- 350 ESC module
- 350 knock sensor
- ECM & Injectors for 350

Also it seems like it won't be a factor but will there be any issues (aside from strength) bolting the 350 up to my T-5?

Thanks

You can use the same esc and is. You will need a custom tuned prom.


I have no idea of intake to hood clearance (I’m sure someone will chime in.)

You may need to increase fuel pressure. In order to do that get a TPI pump or a pump that will do more than 11-12 PSI that the stock pump usually puts out and a fuel pressure regulator.
