Been looking at pistons gonna need 4.035 or 4.040 bore.
Hard to find but found 4.040 but selection is very limited

anybody have a lead on off the shelf pistons that bore?
stock stroke!

 

Wiseco makes a shelf 4.035 piston. They will also do custom bore size on a current design for only $30 more. I have a set of their -11th turbo pistons in 4.040 bore.

 

i saw the wiseco 4.035 but it was for a 4inch stroke not stock stroke
Maybe i over looked it!

 

K444X35 is the pn for their -11cc dish 4.035 bore stock stroke piston set.

 

Thanks but I need something flat top or 4cc dish

 

Looks like they have removed all the 4.035 part numbers from the 2014 catalog. You could probably call them with pn K398X35 and get their flat-top with 3.2cc valve reliefs for a 4.035 bore. For a custom bore on an existing piston design, they are pretty accommodating and have a pretty quick turnaround.
