help identifying slant 6

Some info I saved from a web page below. The years appear sketchy for slants.

The main identifier is said to be the one on the passenger's side top of the block, behind the alternator bracket. All I see there on the slant in my 64 Valiant is "V 22 8 14", but perhaps the paint hides more. My casting# of "2463430-8" decodes to a 1966 225.

Your casting# appears to be later than 1966 and a 225.

A few other scraps: Early slants had 3 core plugs (driver's side), with the middle one higher. Later ones had 5 core plugs in a row, like a 1974 I have. Those blocks are said to be stronger. "RG" blocks (225 cu in) are identified by a longer heater hose between block and head (behind thermostat). Even then, it is hard to get a new one on, so I used silicone hose. Later engines did not have the removable aluminum tubes for the spark plugs. That was integral to the head. Early heads are termed "drool tubes" by swags, but an advantage is that one can remove the lifters without pulling the head, and the tubes are another thing slants share with hemi engines.
