Greetings from snowland y'all,..I'm rebuilding my 2000 Z-SS and leaving as stock with the exceptional of a very mild cam and upgraded valve springs...I see the EngineTech company from Tx. has very reasonably priced parts and want to make sure that their pistons are up to snuff..I heard Jasper uses their kits exclusively so if anybody has experience good or bad with them please let me know...my engine needs a rebore to next oversize so trying to save money wherever I can
