Highest flowing sbm heads?

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.

He says its 3100 LBS. That's not exactly light in my view. He has 3 cars running 9's that all weigh above 3000 LBS.

My demon w/std stroke 360s went 10.30s at 3100lbs and w/stroker 360 at 418 c.i. has been 9.60s 1/4 mile and 6.0s 1/8th mile.

The others:

2009 418" build dan smith built new 9.96 131.82 6.23 108 1.30 60 foot best to date 9/15/09 8in 727 430 dana 2860 lb 3040 lb w driver
My friends 64 Dart w 414c.i. 360 and my race ported eddy RPMs went 9.59 at 137 today. 3050 lb car.

Even went onto say that the Eddie heads on the dart only flow 275 cfm:

my friends 64 Dart"..... thinking that's the one that just split a bore in a block I was reading about
It did start drinking water after the second pass yesterday. Engine is old and I sonic tested the cyl walls a couple winters ago and they were on the thin side, but a lot of cash was already spent so he had to use it. Just used his car as an example of capabilities of eddy RPM heads. Only flowed around 275 IIRC. Those heads on a 318 would feed it very well and only a high 10 second goal, easy. $6000 budget would get him an engine to do what he is looking for.
