Well, in a pm you said the car would go slower with the new pistons and that didn't happen. Without playing with timing, jetting, or anything else engine related it went 10.70 in crap air. Now it won't go 10.60s. You are batting .500 and heading for zero.
Yep, more horsepower.
The Homewrecker ran 10.70 with a density altitude reading of 3,500 ft.
On a cool day with low humidity and high barometric pressure, the DA could be at 1,000 ft. or less.
I think the engine could be making about 50hp more at 1,000 ft. than it was at 3,500 ft.

if things were different , they wouldn't be the same
same air? It won't do it .
obviously , good air is going to give you the hp needed.
equally obvious , it's a damn good car !

And how many have you built & raced sirif things were different , they wouldn't be the same

More HP gets it done. Better air? More HP. More compression? More HP. More HP More HP More HP! I too think if the air was cooler and much better for making power, the car DOES go faster. Wisconsin has been in a patch of hot/humid air for awhile. Summer in the midwest. Big deal. If the car is running good, in cool air...I think it gets it done. 
10.70's this time of year should easily equal 10.50's in the fall. 10.70's the first time out with a new combination will most likely drop some more with tuning even in the same conditions. I predict you'll be well under 10.50 before the end of September.

So you state that a major change would be needed to go from a 10.70 to 10.60s, then proceed to state that any change such as weather would qualify. Of course if everything is the same the car will run the same. So where were you going with your post? You you either felt the need to post the painfully obvious or now you are back peddling because you realize the car as built is very capable of running 10.60s or better. As for the piston design, I agree friction losses are greater but they do not cancel out the gain from the added compression. You stated in your pm the car would be slower. It is not. How you can still claim you are right on that is beyond me.if things were different , they wouldn't be the same

Went back a few pages and never found what comment made about the pistons. Maybe, just maybe, the good Dr. meant that once you have maximized a tune and the car runs it best,, gaining another .1 takes a substantial change in hp . The experts claim one point of c.r. can be worth 15 to 25 hp. I tend to believe 10 hp is closer to the real number. Will 30 hp deliver .1 gain in performance? I don't think so but these are just opinions. But what difference does it make? When buying pistons for a race engine, I want all the c.r. I can get.. Is that right or wrong? Who knows? That is what makes this sport so much fun. We build using opinions we have formed and then go out and have fun, always hoping for a fast car. Could we have done better? Monday morning quarterbacking is easy.
We all know good air compared to bad air can be a .2 change.. I would bet what little cash I have that Dan's car will run 10.50s in good air,,,, but Dan ain't gonna be satisfied with 10.50s,,, he will do what we all do and make changes in the future looking for 10.40s. Its our passion and we love the challenge.

Dan , no disrespect meant in my comments , on here , or pm .
my thinking was simply that the increased compression ratio , was going to be offset ( no pun intended ) by side loading into the cylinder wall .

Really like your comments Ronnie,
The only real racing i have done in the past was in my 56 belair.
I got it as fast as i could go with what i had and thought more HP was what i needed
Got more HP then went backwards with traction, ended up slower than i was with less HP,
i love the game (trying to go faster on a budget) and the solutions people on here come up with
Cant wait to be asking all those dumb questions that all you guys have already forgot about when i get the 61 going

Lookin' good, Dan. Thanks for posting.
