X....The manifold will bolt up, it's made for a 429, 460 or 514. The carbs are a good question. There are plenty of threads about dual quads and what carbs to use, some use the Edlebrock but most seem to use the Holley's, just do a search for dual quads .
I chose the 600 Holleys because I like working with them and I like the look. The Blue Thunder manifold has the correct 427 spacing between the carbs and the aftermarket dual quad 427 linkage is made to work with the Holley's.
I guess performance is the next thing, what size carb and do you use vacuum or mechanical secondaries. That should be determined by engine size, horsepower and the type of driving you do.
