I was replacing some old vacuum caps on my 76 and after starting the engine up I noticed a hissing sound coming from what I think is the EGR valve. Thing is the PO de-smogged the truck when he installed the Weber carb so I shouldn't have an EGR valve right? I'm guessing PO was to to cheap/lazy to pull the EGR and block it off. I'm also assuming I should go ahead and do that. Anyway I've attached a video for reference.

 

Yeah you definitely want to pull that off and plug the hole on the side of the head. Make a plate or buy the kit that LCEngineering makes.

Pretty sure what I am seeing here is an egr valve with the modulator port capped and the "output to intake" venting to the engine bay. ?

Nice move previous owner..

 

All sorts of fun little suprises left by the previous owner. Ordered the block plate!

 

Pulled off the heat shield to start and found this little surprise.

 

420 braze it boys!

 

Haha yep close it up!

 

Or, buy a header from LCE when you order the EGR block-off plate.

 

Headers would be a cool upgrade but I'm on a budget. LCE headers are like 360 and I imagine I might to do some fab work on the exhaust to get it to line up.

Brazing would be a lot cheaper if I can find someone with an O/A torch.
