Only for the '66+ heads. The intake bolts don't match on the earlier heads. For some crazy reason Mopar changed things, and after a short 2 year stint on one design, decided to "improve" it. The '64-'65 273 heads had different intake bolt patterns. Incidentally, the '66+ is what was used on all LA 318, 340, and 360 engines.
With the small intake ports of the 302 318 heads you want to use, the Edelbrock SP2P intake is an excellent choice. At least the port sizes match.
Yeah, the 273 doesn't have the stroke and bore of a thoroughbred so I am aiming for improvements in air speed and velocity. Honestly, it's going to stay the way it is for a long time. I figure it will take me a long time to find a pair of 302's and an SP2P. I used to have both of those but you know how when you finally decide to sell a part you are going to want it back.

the heads that are on the early 273 will serve you well. The D4b although somewhat rare is an obtainable intake. There were also several of them at the last Indy swap as I bought one of them as well. Probably around 5 of them there at the last meet. I will send you a pm for the good heads that come stock on the early 273.
Questions of the day:
I have a set of 73+ lower case control arms with sway bar tabs. Are early/late LCA’s are interchangeable? I vaguely remember reading the sway bar tab is different.

I'm too old to know the interchange year for the LCA but I do have a factory 1965 Barracuda sway bar, brackets and bushings in the garage.
