RE: LS7 dry sump photograph

Nice slide show, thanks.  What is with those piston cutouts?  4 valve cutouts for a 2 valve engine?

RE: LS7 dry sump photograph

Look closely.  The different-sized valve clearances aren't symmetrically placed.  I'm betting that it's a single part number that can be fit to any cylinder in either bank.

Bingo Norm. Chevy V8's have a long history of 4 valve reliefs on the piston so there is only one part number and it can go in any hole. ISZ
