402 stroker forced induction questions

I disagree with all of you since it is not the static compression ratio that is the defining point but ultimately the running cylinder pressure combined with the amount of boost. Or the total pressure running under boost. Careful attention should be paid to the timing of the ignition because the Hyperutecic pistons do not take kindly to detonation. And THIS is where the Hypers get a bad wrap and forged pistons get recommended with the mod to long life under boost.

This crate engine should not have any issues with low boost levels. (Under 10 psi.) Some here have pushed well past that. Read up and on it.

I agree to some extent rumble. I am not thinking about the internals of the engine, as most of the bad things that can happen to the engine can be controlled to some extent by timing control. I am thinking more along the lines of fuel. To be able to run much more than 4 lbs of boost with a 9.5 to 1 static compression engine you will have to raise the octane level of the fuel past pump gas levels or seriously back off on the timing. Both of which are not the best answer.
