340 mopar intake issue

They sell 1" & 2" thermostat housing spacers that have extra ports, you will need a spot for your temp gauge anyway. They also come in anodized colors.

I used one for a sb Chevy (same bolt pattern) just may need to run a sb Chevy thermostat and thermostat housing on top of it. I went with the 45deg Chevy housing so my hose would clear my blower but they have straight ones, the Mopar housing may work as well on the spacer.
