timmy the super victor is the intake to use or the brodix the reg victor not enough intake. i have been doing this for lots of yrs and the engine that your building is fine with super vic. i had a 406 in a chevelle pump gas small roller and it made well over 500hp& 500ftq and went 11.30 with the super vic. it's not that much bigger then the reg victor it's tall with better intake runners. there is no way a reg victor will out perform the super on a 400 or larger small block.
