A few questions

Okay guys, bear with me. I'm starting the research for my 350 buildup. Unfortunatly because I work many many many hours I haven't lots of time for searching through all the post, so I will ask my questions.

First, I need some info on fuel pressure, regulators and pumps. I plan on being between 350-400 fwhp, how much fp do I need and how do I acheive it. I will probably run the 454 TBI

What size injectors do I need to run. I'm staying with the TBI, mainly because it is already there and this is a daily driver. Therefore reliability, economy are issues.

Any help would really be aprreciated.

This is just my .02 but I would say that the 454 TB is a must, I am runnin 65lbs injectors, I would think they would be fine for you but I have also heard that they are very hard to find. 14 psi of fuel pressure should be fine I would think, but if I am wrong someone please correct me.
