A question about a 69 273

Hi Folks,
I bought a 69 273 motor with auto trans. I am replacing my /6 in my 66 Valiant.
The motor has been bored and the tranny is rebuilt. The engine will be assembled within the next week or two.
Thank God for the guys that still do these forms of art. The who did my transmission was incredible the way he just broke in down, while talking to me and 3 other techs that were asking him questions about their duties at the shop. He's been doing transmissions for over 30 years. The guy who bored my block is pushing 70 and was an instructor at a UTI school for a while. He retired and re-opened his machine shop. These guys are amazing, and I am forever thankful.
I was at the Good Guys show in Springfield yesterday and I was talking to the Edlebrock rep at their vending spot. I was inquiring about a intake for the 273 and he flat out said they don't make them anymore. I was bummed. But he said the 69 273 and 318 are the same. It that true?
Also does anyone have a used 4bbl intake for the 69 273?
