Don't know were crankshaft hp is now. With the latest rwhp numbers, I would like to think it is around 540hp. I am very happy with the srtw, it pulls down low and up high.

I have a Dart block locally built 408 with AFR heads H beam rods forged steel crank, tirck flow stage III cam. Petty much the same as a Roush but a lot less money. Anyway I dyno'ed at 401 hp at the rear wheels with a dual plane manifold with a HP 750 carb. My engine builder said if I really wanted to make some power I should go with a Victor Jr and a HP 950 carb. I did and gained 25 RWHP.
So your estimate of picking up 30 hp at the crank with the manifold and carb are right on.
Yea I know there are people out there saying I have over carb'ed it. But, you know what? It pulls like fuel injection. I can be lugging along at 35mph in 4th gear (3.73rear) and punch it, and it pulls no hesitation, just pulls.
I would not have believed it but I thought I would try it and it worked. Down side is 10mpg, but for the amount I drive it on the street it doesn't matter.
