http://www.dragzine.com/news/ford-sm...-chet-herbert/ “There’s actually a very small combustion chamber at 46cc. It is a true hemi but basically, it’s all valve,” says Vrbancic, noting the valve sizes at 2.400 intake and 1.900 exhaust. “There is water going through the head but it’s not a conventional water jacket. It does keep them cool, though.” Herbert also designed a custom 3-piece billet intake manifold in which the center section is actually part of the intake port, according to Vbrancic. Sitting on top is a pair of Carb Shop-prepped Holley HP carbs. Rounding the engine assembly are a Jesel belt drive, Meziere water pump and MSD distributor. With a “small solid roller” the engine makes just over 800 horsepower at 6,600 rpm on pump gas. Peak torque was 671 lb-ft at 5,200 rpm. Final destination is a street rod. |
:cool:

I remember reading about another "hemi" headed SBF a few years ago that IIRC were revving to ridiculous RPM... can't seem to find any info on it now though..
Never seen this one before, but awesome nonetheless :nice: |

Never seen this one before, but awesome nonetheless :nice: Kind of sad the ARAO 32v cylinder heads are just vaporware... would be interesting to see how they would stack up against hemi type cylinder heads. |
Thats not them.. but definitely glad to learn of yet more of these types of heads :nice:
