4 - dished pistons
9- flat top pistons
01 Silverado
Use a bore scope to check the piston type. Earlier 4's had weaker rod bolts or something too. Some of them have different cams. The 4's were in everything under the sun therefore there are a million versions.
well im buy a compelete one so there is really no way of tell right?
pull a spark plug and look in the cylinder with bore scope. theres probably some casting numbers on there somewhere that will be able to tell you too, but im not sure.

maybe you can try taking a small screw driver like a pocket size one take the spark plug out see if you can feel the top of the piston maybeOriginally Posted by rcsilverado99

+1, you can see the dish of the LQ4 piston.
Gone, but not forgotten!
