For a racing class that requires pre 74 American production iron block and heads, with a 370 cubic inch limit, naturally aspirated, where maximum power is everything, how do you think a 4.25 x 3.25, high rpm Hemi would work out? I already have a set of iron heads that will flow 420i 315e. The Wallace calculator says these heads at this cid will make 900+ horse at 10,000 - 11,000 rpm. How high can this size hemi reliably rev, assuming all the best stuff?

What has been done like this already?

How would you build it?
