How does a TBI fuel pressure regulator work?

This vacuum referenced fuel pressure regulator (VRFPR) changes the fuel pressure as the engine load changes. A higher engine load equates to a higher fuel pressure along with a higher injector flow rate. And with a lower engine load a lower fuel pressure along with the lower injector flow rate.

What is a TBI carburetor?

TBI, throttle-body injection, also known as the carburetor with a brain. TBI systems use a dual-plane aluminum intake manifold and a throttle body with two injectors that deliver fuel to the engine.

What is the fuel pressure on stock 350 truck injectors?

Stock 210hp 350 V8 up to 250hp the stock 55lb 350 truck injectors at the factory 11-12psi is fine. from 250hp to 260hp the fuel pressure should be bumped up to 13-14psi on stock 350 truck injectors which will change their flow rating to 60lb/hr

Will a 210cc intake head fit on a 400cc engine?

While a 210cc intake runner head will make good horsepower on a 350 engine its not going to make good low end torque. now with a 400ci SBC that 210cc intake runner will work just fine as you have 50 more cubes to pull air down that runner.
