Hemi Quench

I am guessing they use Devcon to get it where they want it then digitize it,then CNC a blank.
 
WE used to call it a "bathtub" chamber
Did not Bob Mullen do some like these?
And not really quench more like squish to get some turbulance
ignition timing can be reduced
looks like the Canadian outfit makes some nice parts
and Stage V is top notch
I've done several of their BBM Hemi conversions
and
Al Teague ran Stage V on his Speed-O-Motive streamliner
Al's a real DIY hot rodder
35 % for 5 miles on a KB block- better blocks available today
 
Has anyone ever cut grooves in intake valves to get more turbulence? The grooves would look like a turbo vane but like mini vanes. If done on a wedge motor you might to have "vanes" go clock wise in one cylinder and counter clockwise in another cylinder. Another of my crazy ideas.
 
Seen it done many many years ago in an old magazine but I don't think it worked so well. I think the air is coming in too fast for that to effect anything in a positive way.
 
Isn't that the thinking behind the Gen3 head design (that Tom Hoover helped with)?
Gen3 head on top, modified G2 head below. Looks very similar...

Kinda a boss9 copy of sorts, which make great power.

Although the chamber had small “squish shelves” on both sides, the heads did have HEMI-shaped chambers that enabled them to incorporate big valves and generous ports that actually outflowed the Chevy LS1 heads by 24% at 0.500” lift, so the new motor delivered 345 hp and 375 lbs. of torque. That’s 41% more horsepower and 12% more torque than its 360 Magnum, so it was well received in the market and recognized as one of the ‘10 Best Engines’ by Wards magazine for five years in a row.

The location of an accurate vertical transition on the conventional Hemi Chamber platforms was always an issue.

Where did Tim publish 654 cfm and at what Lift ?

I dunno what could for practical purposes utilize that on the current Bore spacings ?
 
i've seen a figger 8 or bathtub design on the hemi head to lower piston weight as well .
 
Since the LA engine and cam-lifter angle was originally Hemi why has no one adopted the Gen 3 head design to the LA / Magnum block?
I guess the question is why? The bellhousing pattern is the same so why reinvent the wheel when Gen3 blocks are more widely available?

The cam is 1.315 inches higher in the Gen III than an La or Magnum. The pushrod holes would be a huge problem.

We never had much success with the BOSS9 Hemi design, we got stuck around 850 hp with it and gave up ?

The Customer was still game to PAY us.... we just had to default to "we weren't comfortable with where he wanted to go", so better he find someone else more talented with it than us ?
I heard he did eventually get up around 920 or so ? but I also heard it cost him $100K to get there ?
