alf4444 --

Since you state that your '78 Blazer never had a catalytic converter (only the California emissioned Blazers did for that year) it also was not originally equipped with the EGR system. That applies for 350's as well as 400's as originally installed in federal and high altitude emission '78 Blazers.

Hope that helps.
