ok don't beat me up. i did post on the super mod bomb board, but as of yet no one has come up with a ans.
question, which way do the pistons go in if they are on marked as on a isb eng. (24valve)
i looked on my old pistons and there is no arrow or "front" on those either.
hellllllp!!!!!
yes i know the hollow side gose down

 

just a hunch, but if they're not marked it probably doesn't matter

 

??? There's no notch or any kind of difference from one side to the other?
Maybe Duner's right, it doesn't matter, this being an inline 6. They were always marked in the engines I built, but I only built V-8s.
Were the old ones marked, or are these the old ones?

How's the rest of your rebuild efforts going? I haven't seen any updates to the original thread. Did you buy an engine stand to support that 24v?

Oh yeah, are you takign pics as you go? I'd be interested in seeing them.
