Wiseco Pistons

[djtoad]

Eagle lightweight crank. Manley turbo tuff rods. But the Wiseco pistons are stamped 6560m855 and I am trying to figure out how they compare to the HD pistons or how hard I can push them. I know the block is .020 over and decked. All components are balanced. I have a nice head done by Force engineering. Just seeing your opinion.

I am running the standard Wiseco pistons at just north of 500whp for about 25k miles now. I have seen a few people go higher than 600whp. Biggest downfall I've seen is some cracking in the skirt area, but I think it's more of an RPM thing (the two personal instances I've seen were 2/3/2 miss-shifts and 11k+ rpm).

I ran those in my old Talon for years and currently in my GVR4.....600awhp+ - both DD cars. Not an issue.
