Stroker small blocks - what intake?

They are ported edelbrock heads. They flow 280/195 at 28 inches. The camshaft is 624/624 @.050. The carb is a 750 dp, an old Barry Grant unit. Do you think I should be using something like a Victor and a larger carb? It does seem to run out of breath upstairs. Exhaust is TTI 2.5 all the way. I am changing it to a 3" headpipe and X, and keeping the 2.5 tails. Thanks for the advice.
