Hi Ross,

Mike and George would be the experts, but i would think those base plates were made in such a way that you do not need the velocity stacks.

i can drive my cars year round here in Georgia. i totally agree that in the dead heat of summer that a "airbox" would be a bit better as the carbs can breathe in air that is cooler than the hot engine bay. however, i still prefer the individual aircleaners as i can work on the motor ( change plugs, minor things) with them installed.

i would consider running the individual air cleaners until euro airboxes can be found.

glad i could help!

this is a great thread, my hats off to Mike at Evans, and to you for sharing this with us.
