Well the "absolute" max it can handle is around 750 HP!
Of coarse this is with "extensive" modifications too mind you.

Well actually he'* got the 4T60-E Trans. The 4T60-HD Trans was in mostly Cadilacs, but never in a Bonneville.
87-91 Bonnevilles had the 4T60, 92-96/97 had the 4T60-E & the 97+ had the 4T65-E.
