6.0 piston question?

[04_f350_6leaker]

Hey guys im putting together the motor in my puller and i have a new set of 020 over mahle pistons to go in. I will be running a bushed s475 and some big hybrids soon so im just looking for some input on wether or not to do any bowl work to the piston like remove the bowl lip or any other material? and if its worth it to coat them?

Personal opinion, cut the bowl lip. Less prone to cracking. Get ahold of Tech Line coatings. Coating the pistons is cheap insurance.

Ok thanks alot thats what i was thinking too. Would it be worth taking a little more than just the bowl lip to get a little lower compresion?

Most people just remove the lip because it's a stress riser, it holds heat in. I say just lose the lip, coat them and run them.

i just did mine,and was recommended that i leave them alone... long story.

Let's hear the story and/or reasoning.

Let's hear the story and/or reasoning.

honestly it wasnt going to do much. also each piston the bowl is not in the exact same spot. so with the equipment local to me,it wasnt feasable to try to do it in the time i had.

unless i was going to make the bowl bigger,without all of the lip,it was not going to be productive.

not to mention it was going to bitch slap the bowl swirl right out of usefullness.

you need some of that lip there to retain bowl swirl,especially for a dual action truck of street strip,and pull track.

I guess it's a loaded question really. It also may be beneficial in other applications more so than ours. DzChey just did his by hand for his 6.4 build, which anyone can read about in the 6.4 performance section. The big thing I saw there was to make sure the pistons are weight matched after.

Kyle, is that with stock pistons? I wonder if the Mahle's are any more accurate, as far as bowl location?

I haven't really read a whole lot about 6.0 pistons cracking or breaking anyways. I know the d-max guys do it a lot on their trucks, but again apples to oranges.

Maybe it's more suited to a puller only where there will be big heat and drivability isn't a huge concern?

exactly

yes stock ford pistons.

Ok, that makes sense. I wonder how noticeable it would even be on a street truck.

Did you weigh your pistons at all, just out of curiosity, to see how close/far apart they are weight wise?

no i didnt.
we built the engine,installed,tunned,test drove,borke it in and got a sled pull,and a bunch of track time on it,within the last 7 days.

Good to hear. I was just curious, head of some of them being off.
