As this is my first build... I'm sure this wont be the first inefficient move I make.
I screwed up and jumped the gun on this deal. Now im hoping I will beable to install the new pistons myself? I assume I need to take the old piston/rod combo and have a shop switch the pistons?
Also I believe the H345CP speed pro hyper piston is a standard compression height piston.
they should be the correct height if they haven't changed anything.
As for weight matching you can do it yourself with a gram scale, or have a shop do it. you'll need to compare the specs before you buy though between your current piston and your next one- word of caution speedpro hyper pistons tend to be HEAVY. A set of very gently used stokc LT1 pistons may be better (they're hypers made by Mahle and lighter- but they have a metric ring pack).
