Very interesting, indeed!

I think it could be the long project of Glenn Bunch? http://www.glennbunch.com/

Glennīs Hemi is 4.5 bore x 4.5 stroke, 572CID, 11.5 comp, with Weber carbs.

Glenn writes on his pages the following: "On a chassis dyno, I got 600ft lbs at 3000RPM and 730ft lbs at 4900RPM at the rear wheels".

Absolutely the greatest stuff!!!
