What are difference between these 2 2.3 stroker pistons
Wiseco 1400hd 9:0 and Wiseco Asymmetric skirt 9:5 ??? I need help on this im building a 2.3 stroker with a 4g64 crank and manley TT rods what pistons will you guys suggest

 

One is asymmetrical and the other one isn't.
One is 9:1 and the other is 9.5:1.
One is called 1400HD and the other is called HD2.
One was released a while ago while the other was just released this year.
One is heavier than the other.

I don't know how big of a difference it'll be between 9:1 and 9.5:1 if you're planning on running pump gas to E85 maps. You don't want to go higher on pump gas. If it's just an E85 only car, go for the HD2 asymmetric.

 

I know that the 1400hd only come in 9:1 and the asymmetric come in 9:5 so basically the asymmetric are the hd2 ??? Ima be running both gas 91 for daily but E85 when i drag the car
