[Diy_efi] Intake Manifold choices SBC carb to TBI conversion

[Steven P. Donegan]

Well, you could use any 4BBL manifold you like and a Holley 4BBL
throttle body and plumb the intake ports for injectors. Given it's a
motorhome type application going for an RV style cam and an RV style low
profile manifold should keep things in the right zone for low RPM
torque. If you're not handy with tools doing this conversion will not be
easy.
