Explain Quench to me.....GO!

I clicked agree
actually squish helps on the early Hemis and 4v OHC motors
on the early hemi we got it by using a larger bore against the early head (which has raised ports in any case compared to the 392
you can do the same thing with the late hemi
you can also run the dome next to the combustion chamber on the side away from the plug
if running big valves you have to radius the top of the block where the intake is flow does not like to hit sharp top of block and neither does the valve
and BBM is about the worst post 1967 915 head
even there the plug and valve location is about as bad as you can get
the 361-413 Truck motor used spark plugs in the 1958 Ford FE locations (same locations later used by the LA engine) so Chrysler did understand the problem- and makes them much easier to change (still not so good chamber but about same as most at
BBM introduction in 58)
so why not in the BBM?
our loss

oops did not notice date on this thread- still good
