Maximum HP in 904 Transmission With the following parts:

Hi,

I have a 1977 Brazilian Dodge Charger...

My question is: What is the maximum of my HP 904 transmission survives?

I did a rebuild of the transmission with the following parts:

TCI Rebuild Kit: 129000
Boss Hog Converter: 3200 stall
Mopar Performance Flexplate SFI aproved

I have a 360 engine with + - 450HP. With 4.27 gear and Hoosier Slick Tires 26x10x15.

My 904 Transmission will survive??

Thanks...
