the 454tbi is 2" throttle blades and 550 cfm
the small block is 1 11/16th and 500 cfm
the big block injectors flow 70 x2 is 140
8x24 is 192

one bottle neck coming right up. one must remember these tbi454 where peanut port headed engies with intake ports smaller than some small blocks..
good luck with your goal of 400hp.. hope you get there..
the data of parts being planned on being used , it don't look good..

your an fyi.. mr 72 in a thread on here "carb confused"

Im terribly conflicted... Carbs

post a 350 will need 750cfm..
now no matter what I think(650cfm) his post on that thread and him telling you you'll get to your goals with a 550cfm tbi.. well.
now if it was a 550 throttle body dry.. no fuel then maybe.. squeak by.. and thats a big if..
carry on..
