casting# block 2202857-7 & intake 4104595 yr??
2202857 is a 1962 block. It is not included on that very incomplete and error-riddled chart reposted by Bill G, which can nevertheless be viewed more easily
here in its original location.
4104595, as others have already pointed out, is an iron 2bbl intake manifold made in or after 1977.
Just a note of caution, be aware that the OE crank in an engine of that era
would've had the smaller rear hub dia., and would also have had a pushbutton trans
if it were an auto.
The smaller crank counterbore in Slant-6 engines was from 1960-1967. It means a small-nose torque converter must be used, because the '68-up large-nose torque converter won't fit. The small-nose torque converters were used on all pre-'68 Slant-6 automatic transmissions, not just the pushbutton-controlled ones of '60-'64. And there's nothing stopping anyone putting a '68-'76 (large-counterbore) crank in a '60-'67 block; the engine the original poster asks about may be a remanufactured item, so seeing the 1962 block casting number doesn't necessarily mean this engine is a no-go in front of a '68-up automatic transmission.
The early stamped codes started w/the "series"(year),then the 1st two of the eng. displacement, then the month day and shift that built it.
That's the prescribed coding, but not all build plants adhered to it. Uniformity of engine stamping was better prior to 1966, then we start seeing more plant-to-plant variance. Still, knowing how this block is stamped would add at least small bits of information to the engine's provenance.
Unless it's been milled off,you'll know exactly the date it was made.
All you'll know from the engine stamping is when that block was originally built up into an engine assembly. And if it's a service replacement block rather than a block originally installed in a car, you won't even know that much.
