Default 416 SC Piston To Wall Clearance

Hello
Please help me to decide Piston To Wall Clearance. I'm currently building up a 416ci Supercharger on my Jeep.

With JE Pistons Ultra Series and I will be running a supercharger around 8-10 psi.

On the Spec Sheet of JE Pistons it says to install with .0035”-.0045” and add .001”-.003” with adders

Bellow of engine specs

- LY6 iron block (416 stroker)

- Whipple SC 2.3L

- Scat 4340 forged 4.0" Stroke Crankshaft

- BTR Stage 2 Supercharge Camshaft

- K1 Connecting Rods 6.125”

- Flo-Tek Cylinder Head LS3-500; 276cc, 68cc

- JE PISTONS Ultra Series 4.075”

- JE PISTONS Ring Seal Kit

- Melling 10296 Oil Pump

- HP Tuners Tune in House



I had a lot Piston Rock with Wiseco Pistons and .0052” กก, pictures

I ran for almost 8 years as a pump gas with the same Wiseco piston and .0038" and without any problem, but now with .0052" (.0040+.0012) it was piston rock.

Here link of the project 402 Stroker N/A.


Iดm thinking now between .0040" to 0.0043" with the SC

Some recomendation?

Best Regards
