Thanks for taking your time and searching for me in the Net! I have checked summit and jegs completely down for the block. For 4776-x is no primary available. I`m pretty sure that a block exists which will be physically the same as the block which i`m searching for. But to know which one it is… that’s another thing.
Slowly i`m tending to get an aftermarket product and good.
Well based on the fact that they list the same metering block for both the 4777 DP carb and the 80783 VS 650, I would assume that a meting block for a 600 would work for you ? It might be worth a try being as there are many millions of 600 Holleys out there, hell I've got two 600 parts carbs myself.
