That's right. I did buy the correct intake for this motor. But, when I had the heads done( burned valve ) that is when I should have gotten a nice set of 318 heads and then just about any sbm intake would have bolted up to that. It would have opened up my options. I suppose I still could go that route. At the time I was thinking of just getting it running good then in a few years go to a 383 I have waiting for a build. However plans change and I think I want to have some fun with the 273!
