70 340 HP handling ability.

That's a stretch, you'll need an R block for that kind of horsepower. Also, 9.5/10 CR is too high if you're going to use a super charger. 65'

I am looking at the Ritter block down the road for another build. The 9.5 to 10 CR was a guess as I've seen the guys run different overdrive to get the Psi that works for their application. 2 questions. Is 700 hp a stretch for the potential of this build 426 with a torquestorm? What HP max would a 340 to a 426 with Milodon caps and a girdle kit be in your opinions? Thanks again for the help.
