I bought a 650 4777 dp off of ebay. I tore it apart tonight and noticed the rear metering block is 4779 which is for a 750. Will this work? Anyone have parts?

It will work, most of the DP's from a 600 to a 800 I believe use the same fuel bowls and metering blocks or at least interchangable.

I talked with the holley tech and they are telling me it will not work since the 4779 had 4 corner idle and the 4777 did not. He also said they will have different circuits.

I guess there is always something to learn, Thanks.
