Is their anyone on this great form running Edelbrock Headers #65273, if so anyone have pictures of them on your motor? They're the only ones I can find that work for my "Smog Legal" motor.

i believe dennis had them on his truck before his 6.0 swap. i am also looking for smog legal headers. But my truck is a federal truck and does not have an air pump so its kind of a pain to find them without the air injection holes. Or thinking of running standard headers but i dont if they would pass for smog.

Year, engine?

What do you want to see? I have them on my 81 350 with air pump, calif. engine. I"ll post some pic in the morning sometime. Not completely hooked up with hoses etc. yet.

1978 350 motor. Just wondering how they run and fitment of the headers?

They fit well. The only issue I ran into was the A.I.R. pump connections on the headers are in different spots that the original ones on the stock manifolds. I'm going to get a couple 90 degree connectors to make the routing of the hoses easier. I have not run them yet, ( need to put trans back in) but they line up perfect with the previous exhaust pipes.

Great thanks for the pics.

Cool! I was wanting to know about those as well and was curious about the location of the A.I.R. pump connections

Mccoleman830 · 01-19-2011, 12:39 PM

What kind and where would I find those 90 degree fittings?

Buick455 · 01-19-2011, 11:13 PM

I Considered them but decided to keep the stock manifolds and just sand blasted and paint them. I also could not find any data to show any considerable HP over the manifolds. I also polished the stock SS air line and clear coated it which tuned out real nice, too bad it runs behind the engine.

Just picked up a pair myself. Mine don't seem so easy to install with the AC and heater in the way. I was debating on sending them back.

That's what I was afraid of. I still have have my heater box and ac box still on. All the pictures i see are of trucks with no air box. Just open firewall.
