hey guys ive got a couple of questions i just got my lt1 rebuilt along with 373 gears, my first ? is ive been looking at the zex system online at texas nitrous outlet for the lt1 for 789 bucks do yall now much about the system,2 ? they put speedpro forged pistons in the car when they rebuilt it and they showed me the pistons before they put them in and told me that most forged pistons have numbers or letters on top of each one is that true????

 

Most pistons are marked underneath. How much are you looking to spray?

I have the Zex wet system on my 95 Z28 and it was pretty simple to install after some guidance from fellow members here"nitrodave" And its been working great every since.
