Got a 1983 k5 blazer engine was swapped from 305 to 350 crate engine. Used orginal intake for Texas emissions. Want to swap Q-jet for edelbrock ( fuel filter threads stript out ) Edelbrock says the 1400 is for 1980 and earlier vehicles. Intake has EGR valve. Just wondering if anybody has tried the 1400 or 1406. and passed emission inspections.
