Wiseco Pro Tru™ Street series pistons are forged from 4032 alloy aluminum in Mentor, Ohio and include rings, pins, and clips for an all-inclusive rebuild. For any build budget, Wiseco has the piston to get you on the road or down the track. Wiseco PTS pistons feature ArmorGlide® Skirt Coating for seizure resistant, friction reduction, and quieter operation.
Dome top pistons in a 396 Big Block Chevrolet engine will generally provide compression ratios between 10.5 and 13.5:1 which makes them a good option for engines with aluminum heads and larger than stock camshafts. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to well over .600 valve lift. 18 degree pistons are also available.
