ok, ive already got a good bit of my parts amassed for my EFI conversion on my small block mopar.

using a painless wiring harness for a tuned port corvette
dodge magnum 5.9 fuel rails
ford racing 30lb injectors
7727 ECM
Edelbrock Victor Jr. converted to EFI

still need a fuel pump, return line, regulator, various sensors, and a throttle body (4 barell style)

also need injector bungs to weld into my intake.

any recomendation for the bungs? looking at quality and price.
any reccomendations on a fuel pump? this car puts out just under 400 to the rear wheels at the moment.
will a 3/8 feed and 5/16 return be enough?
what kind of regulator shoudl i be going with? i was looking at the corvette C5 regulator/filter assembly, but remember that the TPI cars had a vacuum reference to them. the C5 doesnt.
any great deal on 4bbl throttle bodys with GM TPS and IAC that i shopuld know about?

lastly, what to do about a knock sensor. i know the ECM looks for one, i just dont know which one to choose. theres so many.

thanks for any direction you guys can give me.
