does anyone make a plenum box that can sit where a Q-jet would normally sit (for a custom MPFI project)?

to be more specific.... i am putting a megasquirt system on a 462 Pontiac and have the most everything done all the way up to where the carb would sit. i went tomahawk route with 42# bosch style injectors.

i need to figure out plenum, TB, & runner. any suggestions? i *think* i want to go with about 50% volume ratio, to end up around 230 ci plenum volume. i thought something might already be available? but.... seems that everyone has ended up fabricating something.

thanks,
Scott.
