Piston to wall clearance

[dusterkid]

My dad picked up a set of used speed pro L-2266F 30. Anyone have the spec sheet on what the piston to wall clearance should be? I messaged Speed Pro but haven't heard back yet and was hoping someone might have the specs.

Ideally, 4.3500 would be the block bore. The clearance would be machined into the piston.
Just do the math after you measure the piston.

Going to be around .004-.005"

8 to 1 pistons for a truck motor.

There were forged pistons for street use that ran with 0.002-3" clearance.
