I really like the velocity stacks, but I had to file the circumference of each Holly 94 carb in order for the stacks to fit properly.

The stainless is really nice but I thought the sheet metal screw was weak. I tapped it with an 8/32 stainless screw. Otherwise it is really nice for the price.

The stack is of great quality,I only wish it came in different lengths, so they could be staggered when using multiple carb setups. It is 5" high by the way!
