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 427 Big Block Chevrolet engine with Closed Chamber Heads will generally provide compression ratios of 10.0 to 10.3:1 which makes them a good option for any engine that needs a moderate increase in compression, 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.
