1966 Barracuda 273 Valve Covers Querie

Yes they will fit (all ‘66 273s had solid lifters).
But there are some model year differences in the center stove pipe and pvc mounts.
There all the same.
Thank you Brian for the reply. The concensus is that they will fit. I am now trying to figure out the rhyme or reason why some 273 V8s came with covers that each had a stove pipe for breather Y PCV/cup vs others that had covers with one stove pipe and one hole w/ rubber grommet for the PCV. Thank you. Eric
