92 350 engine chevy?

Yes i have a question My friend has a Chevy 92 truck with a 350. I think it has the tbi.We want to convert it into carburator we changed the intake and has a 4 barrel Edelbrock carb 600.we changed the cam and other small stuff. I believe we have to change the fuel pump. Would we have to put a manual fuel pump?How can we do that.I know for ford we have to change the timing chain cover and add a manual. but not sure about chevy. Would we have to change the distributor also? Need help soon. Thanks.92 350 engine chevy?
These changes will NOT allow the truck to pass a smog test.Can you afford 8 miles to the gallon? Unless you are going to race this truck ,you should reverse action and go back stock.92 350 engine chevy?
I would say the fuel pump will definately need to be changed,the injection pump will produce way too much pressure for a carb and overwhelm the float needle valve. I'm not sure if the fuel tank has an internal pump but if not you should be able to fit an inline pump between the tank %26amp; carb.

Best to fit a pressure regulator too as this will reduce 'surge' and even out the flow.(Malpasi's Filter King) is good.

Sorry,can't help on the distributor but I don't see why it would need to be changed .Hope this helps a bit! Good luck!
First you have to see if the engine has a place on the side( should be on the passengers side) to mount a fuel pump. I would say it probably does not. So your going to have to install either a aftermarket electric pump for a carb or put a fuel regulator to lower the fuel pressure on the factory pump. If your still running the computer you should keep the distributor,if not replace it with a older pre computer HEI unit.
Check the passenger side of the block for a plate that might be bolted to the engine. If it's there then remove it and there will be a cavity where a manual fuel pump can be mounted. However now you might have a problem with the camshaft because the manual fuel pump is activated by a rod that runs off a lobe on the camshaft. the lobe pushes on the rod that in turn pushes on a lever on the fuel pump to make it work. Since your truck has an electric fuel pump in the tank then it's very possible the lobe on the cam isn't there. But then you said you did replace the camshaft so it's probably there...you'll have to check it out. You can eliminate the mechanical fuel pump and use an inline electric fuel pump with a pressure regulator. Gut the in tank electric fuel pump and block the return line and install an aftermarket fuel pump inline someplace close to the fuel tank because an electric pump pushes fuel much better than it sucks fuel. The distributor may be a problem if the computer that controls all this stuff handles the distributor timing based upon air-fuel mixture. I'd buy aftermarket just to be sure. Bought all this other stuff why stop now?
