I'm wanting to convert my 1990 chevy tbi 350 into carbureted. I'm going to.install a mild cam with vortec heads and I'm wanting to run a holley 750 or a quick fuel carb (if they make a 750?) on it. What intake should i go with? How would i set up my fuel system? I was told i need a return style pressure regulator? What brand would you reccomend and how would i run my fuel lines for that? Oh and i am also going to run an hei distrubutor...obviously haha

 

When I did this swap, I removed the in-tank fuel pump and switch to a mechanical pump. I also used a fpr without return line.

 

I swapped a carb in place of the factory TBI on my 89 K5, I opted to keep the factory electronic fuel pump in the tank and just remote mounted a Big End fuel regulator on the firewall. Just something else to think about. It was way less work IMO.
