8BA pistons have 825 stamped on them.
The pistons in my 8ba are stamped with 825. The motor has a rebuild tag from Southern Automotive Engines inc, Owensboro Kentucky, so anyone have any information on these pistons and what size they are?

Re: 8BA pistons have 825 stamped on them.
.0825mm equals .00324 inches. Could that be indicative of something to do with
cylinder bore or piston configuration? Maybe it was some type of assembly code. |

Re: 8BA pistons have 825 stamped on them.
Measure the piston skirt 90 deg from the pin and tell us what u get.This isn't rocket science.

Re: 8BA pistons have 825 stamped on them.
Hey John. New project?
A set of .0825 was on ebay recently... They existed. Just an oddball piston size for when people removed sleeves in earlier engines. http://www.ebay.ie/itm/FEDERAL-MOGUL...-/371014291232

Sleeve was .040" wall thickness,requiring a hole 3.142" for sleeve. That hole was honed to 3.145" that ended up a 3.0625"+.0825"=3.145" That is smaller than a stock 8ba bore.Can't be the combination op has. R |
