Mine would be going on a generous 440 build up. It does come with 2 600cfm carbs but would I be able to rejet them to lower the flow a bit. Not sure that 1200 isnt over kill a bit.
The stock jetting in the 600's is a good starting point
the Cam is going be the issue, Buy as set of the quick change
tops{assuming they are VS} springs and large assortment of pump cams,
jets and such and tune it in ..once you finaly get it right you'll know it :}
