Velocity Stacks

[OldSpeed]

For my upcoming engine build I am intending to run a Reece Fish carburettor and swap over to a stock carb for the winter months.

Anyway they both have a stock outer throat diameter of 2 inches or 51mm.

So what I'm trying to find out is which velocity stacks will fit onto a stock carb?

I'm guessing the most likely possibilities would be Kadron or 48IDA stacks? But I don't have any to hand to check they will fit. If someone could measure the inside diameter of theirs I'd be very grateful.

Cheers in advance.
