Piston recomendation?

[me612]

I will ask the shop what they set my clearances to next time I'm able to speak with them.

92awdlaser and me612 please let me know when you find out. I still have a while before I start my build so your info may prove very useful.

You may know from me very soon. If I get close to enough money back for taxes I am going to get a built engine.

I chose Wiseco because of the piston slap issue with other pistons. Wiseco use 2618 alloy and Ross uses 4340 alloy. They are stronger, but expand more from heat and need looser tolerances causing possible piston slap when cold. My p/w clearance is .003 with the Wisecos. Some people have no slap and others do. I am sure it has to do with the clearance they have set, but the Wisecos have an offset wrist pin hole which keep the piston straighter in the cylinder.

Just heard back from the shop. They told me .005 is what they set the p/w clearance at.
