Different rod lengths for different cylinders?
I was reading some specs on various SBC pistons and came across a foot note and a table indicating use of a specific rod length in 4 specific cylinders.
For example: In reference to piston part # 14011020, a 12.5 comp dome forged piston, the note reads: "use with 5.7" rod in cylinders 2, 3, 6, 7."
There is no indication what the length of the rods should be in the remaining 4 bores; should they be the same or different??
I thought I knew something about SBCs
, but apparently this one slipped by me. What is up w/ this?
Thanks in advance,
P.

Rod length: different lengths in same engine??
Sorry it took so long to get back on this. I misplaced the link and just now found it (while looking for something else, of course!).
Here is the link to the reference info where the rod lengths (for 12.5:1 pistons were spec'ed) was found. Still puzzling to me.

They are just stating that particular piston uses a 5.7 in rod and can only be used in certain cylinders, I am not sure why but you can bet it has to do with the dome hitting something.
You need 2 parts numbers for a full set of pistons and the other part number (14011021) will fill the remain holes using the same 5.7in. rods.
