When I rebuilt my 0-360 I used Combustion Technology pistons. They were all exactly the same weight. I had to replace a cylinder/piston and bought the kit from Superior. The piston in the kit was 13 grams heavier. So I purchased a Combustion Tech piston to match the others. I was extremely surprised to find your piston to be exactly the same weight as the other original Combustion Tech. pistons,!
Really nice set of 8.5 piston
We use Combustion Technologies pistons at our engine shop as often as we can. It's always a great and easy purchasing experience. These pistons are great quality and always makes our customers extra happy to see how beautiful and shiny they are!
This is the first time that I have purchased pistons from Combustion Technologies. Ordering was easy! I asked for a matched set and they sent me exactly what I asked for.
I have bought pistons for OEM and another major engine parts suppliers but, I will not buy from them again. The quality of the product supplied by Combustion Technologies is unmatched in my view. I just wished that they made other engine parts as well.
Thank you for these quality pistons!
