Nothing wrong with the SA Holley Carbs. I've got two of them running just fine after several years each. One is a 570 on my stock motored '71, and a 670 on the moderately built 350 in the K20 Burb.

I do question the need for a 770cfm though. That's a lot of carb, but it depends on how "built" your engine is too.

If you're going to drive the truck on the street alot, the DP will not be as well mannered as the vacuum secondary SA will be. Just food for thought.
