I think you need to get a trapezoid to Holley 2bbl. adapter made. The bolt patterns are different between 305 and 351+ V6's for the carbs. 351 is a trapezoid, 305 a normal rectangle.

You could go the other route and make your intake in to a 4bbl. one. You can do that with a 351 and up V6 intake. Theres pics of one online somewhere, I think I sent you the link once, Fatman.

Either way a carb upgrade is good for the V6. Makes them much more responsive (even though they are kinda slugs) and powerful.
