Pistons

[SappySE107]

Here is the TRW catalogue spec sheet for the 91-95 as well as the 96/97 pistons.

TRW 3.4 DOHC Pistons
Silvolite 3.4 DOHC Pistons

Notice that the 96-97 pistons don't have as much compression distance but also have a dome to them. I dont know the exact amount of compression loss you will get when using these pistons with the 91-95 heads, but it goes against the common belief that 96 pistons raise compression.

The Silvolite pistons are the EXACT pistons used in the 91-95 automatic. They do not list the 5 speed pistons which would raise the compression slightly.

Most any piston ring set will work for your new pistons, but if you want performance, get a set of Total Seal® Gapless rings. These rings indroduce split interlocking rings that virtually eliminate all blowby gasses. The only drawback is that Total Seal doesn't manufacture a specific kit for the 60° V-6. You will have to get a set of measurements off of your new pistons. If you dont know how, look into taking them to a reputable speed shop orn engine shop and explain to them what you need. Someone there should know how to help. Complete instructions are included with the package, as well as a Total Seal decal and beleive it or not, a peice of Total Seal candy. A set like this will run you around $180, almost the same as the pistons, but are worth it in the added torque you get.
