Tow rig. Are you gonna be slingin it to 6000 RPM? Weight really is a moot point on what you're doing. I'd get them if you got a good deal. It really won't make much difference.
Nope, probably max out around 5500 if that. I know it matters more for higher RPM but it's the best place to reduce weight, lighter pistons are always better for gas engines at least. Heard about heavy pistons being better for Roots-blown applications but not entirely sure if I believe that's still true with modern tech and doesn't apply to my build anyway. But yeah overall I'm not too worried about it.
Funny thing a set of those pistons .030"-over is around $450 but standard bore is around $700, not sure what that's about but I really hope whatever core engine I find is bored .030" lol. All the cores I'm looking at are either low-mileage and still running or recently rebuilt so I can minimize the amount of machining that'll need to be done. Preferably just a light hone (torque plates???), mayybe mill the decks depending on where they are and most likely balance the rotating assembly just so I sleep better at night lol. Not trying to pay for boring if it's not needed, nor square-decking which is why I'm leaning away from a tight-quench build. My understanding/experience is the factory block machining tolerances SUCK and the decks tend to be all over the place, also heard the factory balancing leaves quite a bit to be desired. Trying to be realistic with my goals though and not go hog-wild with blueprinting.
