But I have read and talked to other racers and the acceleration rate of the engine maybe just as important as the max dyno numbers. I attended a Darin Morgan seminar, and he talked about designing heads that flowed great, dynoed great, but were a dog at the track. He went into the importance of velocity of the port, and engine acceleration rates of the engine. Chatted with a pro stock owner at the track one time, and the same thing came up, acceleration rate of the engine, how fast the engine is able to accelerate under load. Just trying to throw something out there for you to think about.

Alan, I know you probably can't give away much but I was under the impression that the piston was shaped to to yield the absolute minimum volume in the cylinder ? So in other words the valve pockets and cylinder chamber shape with some minimal clearance and the compression ratio is whatever that yields ?

Alan Prusiensky OP member A Joined: Mar 2018 Posts: 104 New Jersey	I stumbled on to the dome back in the middle of 18 and I didn't really figure it out 100 percent until a couple of weeks ago. I always found in pretty much every engine I built put the flattest piston you can make and you will make the most power. some reason that isn't what the Hemi wants. I have a idea why the charge doesn't swirl when it enters the chamber with a flat piston it tumbles. What is so crazy I have taken apart a lot of pro stock engines built by a lot of smart people and what I have found they all have pretty flat pistons. If I make my piston flat with the exact same compression my motor will be done 75hp.

I'm pretty much done with trying different hone stuff this is been working pretty well lately.
