Can you look at the 'running' kernel's config to see if it's indeed the one you compiled (provided you enabled support for it during building - see /proc/config.gz)? Eg something like 'CONFIG_X86_64=y' is set.
Is the machine you're building on 64-bit or 32-bit? I hope you used a 64bit compiler for building your kernel.

Generally, After building a new kernel, I issue 'update-grub' command on my ubuntu box to add proper entries for the newly built kernel in the grub configuration file, but I think 'make install' will take care of this as well. However, as you've confirmed that you've successfully booted from the newly built kernel, which is still being reported as a 32 bit kernel, therefore we can safely reject the case of incorrect and or missing grub entry.
Do you see compressed x86_64 bit kernel image(vmlinuz-<version>.x86_64) under /boot ?
