Admittedly, the voodoo magic that is EGR is not something I understand. My car has it from factory, and supposedly it helps with fuel economy, but it seems like a hassle to maintain and needless added complexity to choke out the performance.
I've been considering moving to a 4-Barrel carb, which means also replacing the intake manifold. The factory setup on the 318, with the Carter BBD 2-barrel and the stock intake, works fine for a low-speed cruise around the block, but... you know...
So I've been looking at the offerings from Edelbrock for 4-Barrels and intake manifolds. They have options with and without EGR, and with and without electronic choke. I've pretty much settled on an electronic choke, but I'm not sure if I should also kick the EGR to the curb. To me it seems like a great plan, but since I know so little about it, I want to solicit some opinions first. Is removing the EGR by changing out the intake manifold a good idea?
I don't want to mess around with Holley carbs. I know significantly less about how they work, and would rather stick to what I know. For reference, these are the two options I'm weighing right now:
Option 1: Intake Edelbrock 3776: Performer 318/360 Intake Manifold SB-Chrysler 318-360ci 1972-86 - JEGS High Performance | Carb Edelbrock 1400: Performer Series 600 CFM EGR Carburetor with Electric Choke - JEGS High Performance
Option 2: Intake Edelbrock 7576: RPM Air-Gap Intake Manifold SB-Chrysler 318/340/360 - JEGS High Performance | Carb Edelbrock 1406: 600CFM Carburetor with Electric Choke - JEGS High Performance
I like the idea of having the raised intake runners for thermal's sake. With the tendency of modern fuels to evaporate, I'm much more inclined to keep the heat away from the carb, and especially the bowls, as much as possible.
Any other tips and tricks on the 2 to 4 barrel conversion process is welcome, since I've never done this before.
