many people have used aftermarket pistons...as for topline im not sure, either way id stick with something that most people have experience with here (i.e. wiseco, je pistons, ross ect)
i have also bought some wiseco pistons for my stroker build uplivnthedream said:i have wiseco 8.3:1 pistons in my 6bolt. havent started it up yet. but that was my decision for pistons.
That depends on your piston to wall clearance and ring selection. Also if you have coated pistons the friction is less. A .020 bore will also remove the cylinder taper and result in less ring wear.dsmbuilder said:Forged pistons wear the cylinder bores alot more than cast.
