I know this is for a 750 & 780 carb, is there going to be any problems using it on an 850? This is the kind of stuff you run into when buying off the web.

I think I found it through the all-carbs.com site. Needed that info when I had a 4780 that had a vacuum-secondary metering block in it..."dang, why no secondaries?"

He's easily found in the engine forum. He can help you. I have no use for any of these OE Holley metering blocks. Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
