BBC Piston Identification Help Needed

mannymen · 01-09-2011, 12:30 AM

I have a set of BBC pistons .030 (4.275 measured) over open chamber pistons, but there are no markings on the dome to identify who makes them and the actual application they are for. 7 of 8 are in great shape

The piston side skirts have horizontal casting lines on them and underneath the dome there is a letter A with 3 dashes stacked on each side of the letter. There is also the number 4 stamped under the dome.

If anyone can provide any info it would be much appreciated.
