Royce, you are right it was an open chamber head. They were bb-2's and he did run 110 or 116 octane in it.

Do you think that an increase in horse power is due to the quench in and of it self, or due to the fact that with the proper quench you can get away with a more aggressive tune due to the fact that it is less sensitive to detonation???? what would the power difference be between the 2 motors we are compairing????

That is a problem with the hemi head designed motor. The chamber above the piston at top dead center is so big and you have 2 areas on each side of the plug to get the burn to..... The orginal hemi was a tuners nightmare until they figured out what was going on. They needed so much spark lead to get it all burnt and then just a little more would put them into detonation and lift ring lands.
