1970 Duster Battery Size?

I have a 1970 Duster that was a 340 factory car

Currently has a 440 (1969 block) swap

I need to get a battery for the car and am not sure what size will fit

I measured the battery tray and it looks like its 7" x 11" (inside the tray lip)

It appears as if I can clear an 8" to 9" tall battery

Thanks for any and all help and suggestions
