best piston for 426

6 posts in this topic

an OEM piston is the best in my opinion. I wouldn't mess with any of the aftermarket stuff. I have heard too many horror stories.

No horror stories here, just lots more low end snap and midrange pull. Try a Wiseco 13.5:1, you will be impressed.

I'm getting ready to do a piston...do you have to run race gas with the wiseco 13.3:1? If so, 100%, or can you gut it 50 or 75 percent with pump premium to keep the death rattle away?

Thanks,

Birdie

I run 100% race fuel, but others just run pump gas like 92 octane with no problems.
