What's the cheapest fuel injection setup that will work good on my 350? I know that's a rather general question so let me give off some more parameters. I've got a stock engine now, but I plan to bump it into the 350 to 400 hp range next winter. I'd like to run Vortec heads, but if it's not possible with my intake options, I'd reconsider. TBI can be had pretty reasonable, as can the 2D projection. But TPI is more expensive. This is mainly a low speed 4x4 truck. Not much street driving. What's my best option on a major budget to get the no stall feature of injection?
