Fuel injection to Carb
Hey guys can anyone tell me what I have to do to change from fuel injection to carb.I have some questions that I havent been able to find on the net. 1)If I have a fuel pump in my tank and a fuel regulator, can I use this by adjusting the fuel pressure down low enough for the carb. 2)Would I have to go from my intank fuel pump to a mechanical pump that works off the cam or can I go straight to the carb.
I have to ask...why?

There is an article in the current Super Chevy magazine talking about carbs on LS engines. They pretty much tell you what is needed to convert to a carb but it is meant for an engine transplant into a classic car.
The biggest problem I see is the electronics in a corvette.

me too. fuel injection is the cat's meow. i had a turbo car at one time with a big holley carb sitting on the suck side of the turbo. it was tough to tune for a number of reasons. then i let the car sit for a couple of years and the thing dried out. when i went to restart it, the carb leaked requiring a rebuild.
tuning the carb was a pain, finding the right jets and so forth. and you had to take the thing out and partially apart to change jets.
i have been playing with programming a subaru WRX for about a year. i go back and forth between e85 and high test. using a wide band o2 sensor and some other things, i simply make adjustments to various tables in the ECU. i maxed out the injectors so i got some larger aftermarket ones and re-programmed the ecu for the difference in required pulse widths at various fuel pressures.
if i was putting a v8 in an old car, the first thing i'd try to do would be to find out if i could use a programmable fuel injection system to replace the carbs.

This of course would be the equivelant of putting biased ply tires on as a replacement for radial tires, or drum brakes as as replacement for disc brakes, or a million other analogies, so I too am curious.
