As many on here likely do, I have been collecting parts for a few years now and have some forged TRW 2289 .030 pistons I'd like to run in my engine when it comes rebuild time. Also just took delivery on some .030 Perfect Circle rings (circa 1978 according to the ink stamp).
Are the 2289's considered the LPG pistons?
Do they have any effect on compression ratio?
Lastly, being NOS they have their fair share of knicks and scratches but nothing I would consider critical; what should I look out for and is this common?
In other words, they don't look like a set of Tom's custom Ross pistons by a long shot!
