How much is too much dual quad

Have a buddy that ran the stock 8bbl intake on a 383 with 2 carter 625’s.
Ran fine, just wasn’t very fast.
Picked up a used Offy 8bbl...... basically no difference.

Was quicker at the track with a DP4B and a 750.

If you just want it for the looks, it should run fine if you get the carbs dialed in...... but it’s far from the best in terms of trying to make power.
