Re: L:88 piston ID
Left it at home so will post later. I do know that the pistons do not have an over bore size stamped on top so assume it is a std. bore.

Re: L:88 piston ID
Here is what I THINK is stamped on top of the pistons:
L2808A. I am unable to get a clear shot at the stampings due to my scope not having an optical extension with a "memory". I can not bend the optic cable in a stationary position in order to get a good view of the lower top side of the piston where the stamp is.

Re: L:88 piston ID
That is a TRW number. If you call them and get the right guy they will sometimes go into the archive and tell you what it is.

Re: L:88 piston ID
It's probably an L2308 which is correct for an L88 427. Now it might also have another stamping showing the oversize, like .030 or .060
