I've been offered a sidedraft 45 weber on an L series manifold with a custom made cold air box to use on my 1600 autocrosser.

I'm wondering if this carby could be run on my stocko 1200 without much drama.
Obviously i will need an a series manifold but will the carby be overkill for a 1200?????

(this setup will only cost me $200.00 dollars)
