Fast VS BBK Throttle Body
I'm getting a BBK intake manifold for my 99 Corvette Hardtop, but i'm wondering which throttle body i should get. Fast 90mm T.B. or BBK 80mm T.B. BBK is cheaper but Fast is bigger. What do you guys think I should get?

Let's first say that I'm no fan of the BBK maifold. More weight and almost no gain over the Z06 manifold ( I don't believe the advertised 15hp hype.) I don't think a 90mm TB will fit on the BBK. All the specs I've seen say the TB opening on the BBK is only 85mm. BBK TB is only 2mm bigger than stock. A ported stock TB is your best choice.
