Arias piston

Arias used to offer a "shelf" dome piston for standard iron heads.

Anybody know what kind of CC the dome was on these?

I apologize I do not have a part number

A couple years ago I got some "shelf" SBC pistons from them for a 4.030" bore having a 1.250" compression height which had 11.5 cc domes. A big block Ford would probably be close to that.

They were Arias pistons in the "600" kit which Ford Motorsport offered in the late 90's.

Call CP. They should be able to accommodate you.

Thank you gentlemen.


With way to much time on google I was able to locate an old Arias catalog. They list the dome at 10cc

I believe CP bought Arias for the sport compact business . I don't think they are making any of the V8 stuff Arias used to make.

I believe you are correct.

I ran across a used set of them to use in a budget throw together deal and trying to get an idea if I can get enough compression in the engine to make due. I think we'll be good to go if it's close to that 10cc advertisement.

I had a set of those. I cc'd them and they were 11.5cc
466CI, fel-pro 1018, 77cc chambers averaged 13.4
compression.

Perfect! I should be able to get where I want to be with 66cc Chambers then

They should still have all the engineering data what went with the company.
