And were not talking about strokers or anything fancy.

standard, +.020", +.030" (most common), +.040", +.060"

I don't know of any others, but there may be some. GM also offers pistons in +.001", but this is, basically, for standard bore engines which just need a light honing to clean them up or for "high standard" standard bore engines.

The above piston oversizes are available from Federal-Mogul/Sealed Power/TRW (all the same company now). All of the above sizes are available in cast and hypereutectic cast. I don't know, at the moment, if all are available in forged.

Any automotive supply house should be able to order them for you.

Joe,
can the original 11 to 1 L46 pistons still be ordered? If so, are they forged or cast only?

The 1969-70 L-46 and 1970 LT-1 pistons are no longer available from GM. However, reasonably close replacement pistons can be ordered from Federal-Mogul/TRW/Speed-Pro under their part number L2304F. These pistons are forged, as original, and will produce a compression ratio of about 10.6:1.

A better choice would be Keith Black hypereurectic pistons, but that's another story.
