I see Summit is now offering Holley carbs in the standard zinc dichromate finish, and also now in polished aluminum, which appears to be cheaper. Any reason why the aluminum should be avoided or discouraged over the standard Holley carbs?
I believe the aluminum finish would oxidize over time whereas the dichromate is more durable. I was just looking at the 660 center squirters with shaved choke towers.
PS I know that they're discontinued.
