525efi pistons.Manley or JE?
 

Standard pistons.What are they?

i believe pistons are j&e and rods are manley.

So 525's have JE's?

I was told by Merc. Racing and the a guy at the SEMA show in Vagas at the Manley booth that they are Manley piston. You could call Merc. and Manley to make sure.

Manley = rods
J&E - pistons

Anyone know for sure

525's have JE'shttp://www.bdoh.info/7.jpg

Every stock 502 I've ever been inside of has had JE's. This includes 500EFIs.

Haven't been inside of a 525

JE piston in the 500EFI and 525EFI. Call JE.

Thats what i believed.Exactly the same piston as the 502 Gen VI crate motor,giving 8.75 compression.
Was told recently by someone who should know better they were Manley.Mine definetly have JE's.

525 efi have J&E pistons and K1 technologie rods..

I had to repalce one last year due to a droped valve. Ordered from Merc and got a Manley. No part # though.

i have taken lots of 525's apart and they did come je-700 pistons and some came with manley .the je's will have je700 cast under the dome the manleys have no marks on them, the domes are the same on both .and yes manley rods.hope this helps
