Hi Guys! Because my 4 barrel Carter Thermoquad leaks i bought a month ago a 1406 Edelbrock. Yesterday we wanted to replace the Thermoquad with the Edelbrock but we had some problems.
On the left side (in the direction of travel) is under the carburetor an EGR valve and no place for the linkage of the Edelbrock carburetor. My plan is to remove the EGR Valve and close the hole with a cap.
What is your opinion?
Before deciding, check the EU regulations. In some places -- most notably California -- you can't register your motorhome if the EGR has been removed. So, does EU have vehicle emission inspections before registrations? (The inspections may have a different name.) If so, what does the inspection entail and how are they done?
Alaska had/has local option emissions inspections. Fairbanks did away their emissions inspection but I think Anchorage still does. The inspections started with a visual inspection to ensure all applicable OEM components were still in place and connected. Among other things, a missing EGR automatically meant a failed inspection. You then had a choice -- bring the vehicle back to OEM configuration or register it for "summer use only."
One option is a riser plate. There's arguments for riser plates, mostly because riser plates help keep the carburetor cooler. Downside is mostly clearance between air cleaner and hood/doghouse. The doghouse on vans and motorhomes traps heat, causing carburetors to run hotter. So, there's a strong reason for using a riser, especially a non-metallic one, on a van or motorhome.
(I've mentioned using small marine bilge blowers to reduce heat in the doghouses.)
Because you're going to a dual fuel system, clearance is definitely a concern for you if you choose a riser.
Contact Edelbrock tech support. They've almost definitely run into this before and know exactly how to solve the problem.
Personally, I'm inclined to remove the EGR,
if it can be done legally.
