Re: 98 5.7 vortec efi conversion to a carb
It is a drop in....you will need a vortec intake manifold and regular hei ignition;you can use your 86 ignition if you put the later drive gear on for the roller cam.
AC Delco makes a nice inline electric pump....6472657....
Your 86 should not have an in tank pump as it is a carb truck
