Title: Which EGR Valve?
Post by: biscuit41 on June 04, 2011, 12:25:14 pm

Does anyone know which EGR Valve had a flange like the one in the picture below?

I am using an old Holley Street Dominator intake and my stock egr valve doesn't bolt up to it.  I have been searching and can't come up with anything. 

Here is a picture of what my EGR looks like.  My truck is a 1985 C10 that has a 350 in it.

not sure, at first it looked like a spot for the coil type non-electric choke

That is not for egr. That is for the probe for the hot air choke. I think i have a picture that has both right next to each other on my stock intake.

My EGR is on the lesft and hot air choke tube is on the right. I blocked off my egr and part of the choke probe broke while i was rebuilding the engine.
