ZL-1 waterneck housing

[tufrat]

Intake # 3933198 for the ZL-1 it has a different thermostat housing (water neck and spacer)does any body know why this is so different? Do I really need it? and does any body know where I can find one. Thanks Mike

To my knowledge, the ZL-1 intake did not have a spacer or unique thermostat housing.

ED's correct on that. Should be no different than any other big block.
