[TacomaNC4X4]

im gettin my 05 400ex bored to 416 and i cant decide between the wisco 11-1 or the JE 10.8. which one is better. which one do yall perfer? is there a noticeable power diffrence between the 2?

[TacomaNC4X4]

one more question, can i run 93 octane with that?

I'd say Je .. From what I've heard they are better pistons.
I had a wiseco in my 416 and it worked fine.
And yes you can run pump gas with bolth pistons no problem.

11:1 will work fine with 93 octane on an air cooled motor.
