Highest flowing sbm heads?

The floor is very flat on my Edelbrocks which surprised me but they managed 288 cfm on a 10 " bench. In my view there's more than enough airflow available to make power but actually using it is another story. Dan Smith has a set of Eddies running 9's but says he prefers the 587's himself and looking at how his car runs has no problem using everything the head provides.

Got a chance to meet him at Bowling Green back in September. His stuff runs hard, and he doesn’t baby it..lol
heck of a racer.
That all said, looking at his Demon, I think that car is probably pretty darn light. Getting a stroker anything in the 9’s with a light car isn’t rocket science.
Pittsburgh racer has done it for years. he is very handy.
a guy on here has been 10.10 with a 3250 pound car( very impressive)
Vic Bloomer has been 9.60’s with a stock stroke 340, iron heads with 1.92 valves.
But none for of these combo’s is making much more( if any more) than 600 horsepower.
Its not hard to believe a stock block can live at that power level, you starting getting above that, you are asking for trouble.
