I've been internet shopping for a set of pistons for the 396 LT1 engine build for my son's car. I've come across pistons made of two different alloy specs - 2618-T61 Forged Aluminum and Forged 4032 High Silicone Aluminum alloy.
I came up blank when I tried finding a site that compared one material with another. Does anyone know the advantages/disadvantages of one Vs the other? Thanks for the help. Jake |

Thanks for the response. I had already read that one and found another one on Diamond Piston's site. Just looking for still more info though.
So far, seems the 2618s are the stronger of the two. Jake |

I just bought a rotating assembly from them. They were nice to talk with, and didn't seemed rushed to get off of the phone. I would compare the prices of both items. It looks like they both can take some abuse, so it depends on how you plan on using the engine (and $$). I went with the SRS, since I am putting a power adder on.

Yes, the 2618 alloy are the stronger of the two. They get installed with more clearance because they expand more. But, they are stronger. Most people would recommend them for high power, high rpm or FI applications.
The 4032's are what I used and are a compromise to provide extra strength, miminize the raw-raw-raw sound at cold start-up, but still avoid hyper-crap catastrophy. Keith Black's site has a good write-up IIRC. |
