My later catalog dated 1975 lists CV736C as being a replacement for the 66 396/235 or the 396/360 and the 396/375 engines.

It seems the earlier CV691C, that was discontinued around 1969,was for the 66 396/325.

But was it also used for the 360HP and 375HP engines is 66? If not, does anyone know the number for those engines in 66? Thanks.

I just found some information that in 69 the CV691C was replaced with the CV736C. Was the CV736C valve the one that came one the High Per & Sp High Per engines in 66?
