Thanks guys for all your help. I'm still not sure about a few things.
Will a Galaxie stepped tri-power intake work properly on my 63 t-bird? What oval air cleaner cover with 3 carb holes come off of? Also why is there a linkage attached to the air vent on the carb? one of the 3 have a round vent? Also will original 427 cobra rocker covers fit my 390 with the above mentioned setup? And where do I find a long throttle linkage rod for my tri-power project?
Any help will be appreciated, Thanks hiet
