I ask this because I may be in this situation soon. My heads are deck 30 and I have to check P to V to see how much bigger I can go with a cam .I may have to flycut to make it worth changing to a bigger cam. I made 523rwhp and 543 rwtq on a little 75 shot and plan on spraying more. I have a stand alone system now so I'm ready to up the spray. I was thinking about a set of mahle pistons but I have a 1,500 mile bottom end that is in perfect shape and it just dosent seem right to tear it apart yet.

 

No one ?

 

my buddy just flycut his pistons when we did his H/C swap, he hasnt sprayed it yet, but hes hoping to hit it eventually with a 200 shot

 

Tons of people spraying on flycut pistons. You're mainly taking material out of the crown and not the ringlands so you're not losing any real piston strength.

yea, i've never seen the deck of a stock piston melt before the ringlands went.

 

 

Thanks for the info guy's. I plan on jumping from a 224/228 to a custom 240/245 or something like that. I hope to see som big gains

 

if you are bumping up on the spray, just be sure to get a good all around cam. alot can be had from a good nitrous cam
