Edelbrock heads on a 340 with KB243 pistons

?

I would re write that.
Quench/squish keeps mixing the charge, faster burn, less fuel dense spots in the combustuon chamber, more resistance to pre detonation, gain in mileage due to those things as well as torque because the resistance to pre det allows more dynamic cyl pressure. Tighter the quench...the better the benifits.
As for compression, dynamic ...just divide by two and thats about the octane you need to keep it happy @ optimal timing.


And yet, Chrysler said they went to the open chamber design for emissions and detonation resistance.


Hmmmmmmmm.
