Rich, super thanks for the hook up.
I have the 97mm piston kit ala Gore/Rohrich for my 426.
I sent my cams to falicon for the vernier sprockets, and have my piston on the rotary table to pull some of the weight out of it.
Is there an advantage to the weisco untapered wrist pin? Or can I machine the taper into it?

I am going to set up the squish with the cylinder .010" under the deck, the cometic gasket sets up around .040" right?

Should I machine the head surface or do you recommend the oem volume. I don't have a burret(sp?) to check the volume.

As far as the piston crown...
When you smoothed the transitions, did you radius the cutouts more?
Basically. I attempted to minimize the disruptive effect the cutouts would have on mixture motion in the chamber .
If you look at your original piston you'll see areas where combustion sort of stagnates, and what you can do to try and wake it up in certain areas. I tried a couple of new things in the combustion chamber my 97mm engine but it will take some time before I can tell if it had a positive effect.
The witness of combustion stagnation is the carbon deposit?
Rich, this notion of combustion/flame front motion/control is a bit new to me.
What would you regard as a optimum burn? What are you reading as a witness mark of the combustion motion? Is it the carbon deposit?
What have you changed in your chamber to create a more "complete?" motion?
Crisp jetting on race gas won't leave much in the way of deposits will it? Is that why it will take a while to determine if you are successful?
My oe piston had the bulk of its deposits shaped like a horse shoe, with the open end at the center intake valve.
so many motors to build, so little time!
