Early A 273 valve covers
In 1964 the 273 was introduced to the public.
I'm not sure about the valve covers in 1964 but for 1965 there were different models. The left side valve cover were two models. Standard valve cover w/ignition cable holder and for the four barrel engines there were aluminium finned valve cover with ignition cable holder.
For the right side there were three different styles. What I know of the early 65s had a valve covers w/ignition cable holder, a holder for the heater hoses and a holder for the wiring harnes. In fall of 1964 that was changed to a standard valve cover w/ignition cable holder and a holder for the wiring harnes. I have searched info on production changes but nothing to be found.
The four barrel 273 had the aluminium finned valve cover with ignition cable and wiring holder.
If any FABO members has some knowledge about this it's very appriciated.
