JE Asymetric pistons in LS3
Has anyone used JE Asymetric 2618 pistons in any of their LS builds? They are light at 383 grams.
Looking at doing a 406 build in my LS3 with a 3.9" stroke K1 crank and Scat 6.125 rods that still nets 10.8:1 cr and has a comp hgt of 1.165 using stock heads and LS9 compressed gasket. Using off the shelf pistons in 4" stroke is harder to keep around stock 10.7:1 cr. JE part number is 323983. Thanks, Dan

They were installed in my LS3 based 427 when I bought the short block. No problems.

From what I can find, it is easier to keep the CR at 10.7:1 with off the shelf pistons. Also opens the comp height of the piston a bit and does not pull the piston down so low at the bottom of the cylinder only giving up 10ci. I am still looking at 4" kits too...
