YUP! Like I said Not much.
Really if you want to increase your HP so that it will mean something it will take a lot more than just changing pistons. You need to up the compression a lot then increase the bore get a better cam and carb and maybe add a hotter spark. Then you may be able to increase by 25% to 50% that will mean something. The guys on the Pulling circuit do a lot more than that to their machines just get them to double the HP.

That will include using dome pistons if they were available as a stock replacement. It all depends on how much you want to spend and how bad you want to win. I have high compression pistons and an LP head on my Case LA an it helps but I'm still way off the winner's circle when competing. Walt
