Another CA Emissions thread - The 1947 - Present Chevrolet & GMC Truck Message Board Network

charlieatthedisco · 08-09-2013, 09:12 PM

Boy am I getting tired of CA, although born and raised here when I take a look around the country compared to other states we are f*d.....anyways I was wondering if anyone knows that the right EGR valve is for a 78 350 silverado with a 4 BBL carb. my OEM part number is 17056730 but research shows that this EGR is for a g20 or chevy van from the time period. I need a stock part number, the right one would be most appreciated, actually any CA smog related info or threads would be awesome as well.

Truck runs great besides this damn EGR fing it up!

Thanks in advance.
