Re: what sized carb?
The cam isn't that big, an 800 or 850DP would be way overkill. These carbs are really only for high revving top HP clevo's.
It would handle a 750DP but a 650DP would give you overall better street performance, but top end HP would be down compared to the 750DP.
I view 780VS as a waste of space on earth. Been there done that. Why bother when you can have a DP and have more of everything that matters to performance?
If it was my car I would fit a 750DP because you may increase cam at a later date.
