Hi cdoering. I was looking at this #s decoding post and also this Olds Junction casting #s page, is it possible that this motor is a 1965 casting from the 66th day of that year and that it is a 400ci with C heads on it?

An Olds guy over on facebook was telling me the big valve heads had an X stamped on the pad under the rockers for the #1 or #8 cylinders. I'd never heard that before, but here's a head I recently pulled from a 1968 Toronado engine.

That's a 455 for sure
I thought all Toro intakes had a "T" cast into them (maybe that's the later model versions?), but hey, it does look like a Toro intake. Now here's the question of the hour - what does the rear flange / bolt pattern area of the crank look like? Can you post a few pics up? If it happens to be an EARLY '68 build, it may have the highly sought after forged steel crank, which would be a bonus for you. Here is a pic of a forged rear crank hub:
See the funky notch? That's the "tell" as to whether you have the forged crank or not. I wouldn't get all excited just yet though until you check it out, as only the earliest '68 builds had the forged crank, so the odds are against it with the build date codes I believe I saw. Quick way to determine it though.
