What are better to run on the street making around 500whp no power adders 4032 or 2618's? I searched and seen them both go either way! also are the Probe fps/srs pistons any good they seem reasonable in price along with the Mahle powerpak's?

Those numbers refer to different alloys which have different expansion rates
and therefore require separate piston to wall clearances for many applications
Mahle pistons are really nice...the support bracing underneath makes them
strong, the pins are light weight, the skirts are teflon (anti-friction) coated,
and the top has a thermal barrier coating to help reject heat back into the
combustion chamber. They usually come with the ring set also.

I'm dropping the shortblock off to the machine shop this week and wanted to know what to go with in the event the stockers need changed. I am changing the rod bolts and the shop said it might be more cost effective to get different rods maybe Scat or Eagles if i go that far probably change the slugs too!
