Blaster angle piston?

[trickedcarbine]

I know that for years guys have been using the blaster style pistons due to availability and there are several builders that swear the flatter dome profile creates a bit more power. Can any one elaborate how a flatter piston crown profile creates better power?

 

Just curious because I'm gonna make some changes to the current set up till the hybrid is done.

Flat tops are lighter. I wouldn't think the piston dome profile would matter though, because the actual combustion chamber is gonna be machined according to the piston crown or lack thereof. I could be wrong. I ran flat tops in a motor, then went to new domes and crowned pistons along with a smaller bite and it runs as good or better.
