I want to change my Formula's 305 to a 350 for a small gain in perfomance and before I purchase parts and start breaking stuff I want to make sure all my searches covered everything
My car already has a Catco dual cat system and dynomax catback
It also has a drop base Moroso open element intake
- I will be using an LO5 VIN "K" motor; new from Summit
210HP and 300ft-lb of torque
I need the following
- 350 TBI knock sensor
- 350 TBI ESC module
- 350 TBI PROM, from a Caprice?
- 350 TBI injectors
- My current ECM will work
- My current fuel pump will work
- Stock manifold is a direct bolt on

**If I change the cam I need to burn a chip regardless of which cam I pick, which if I did it would be an LT1 cam and then I should have a pro burn it the chip.

Is this all the correct info? anything to add or subtract

 

Take a look at the roller cam B-body TBI engine near the bottem. It would be a no-brainer when combined with a caprice 350 ecm.
