I know this has been at rest for a week or two but dont forget that the vortec block has no provision for a mechanical fuel pump. The whole is just no there period so your going to need an electric pump.

Perhaps the zz4 timing cover vs the vortec block has something to do with roller provisions? I'm not to savvy on the subtle differences between the roller and non roller motors.
