Mopar purple .528 for a 383?

I thought factory 383 HP pistons sat above deck at TDC, or is it just 340 pistons that do that?

I think it's time to do some measurements on where those pistons actually sit before going much farther...

Yeah the factory HP pistons were 1.932 and if the block is true 9.980 that would be.001 under.
I guess the factory model had pistons.020 over deck height but probably never made much into production engines.
Pistons available now I think 1.928 is the tallest.
But yeah midnight swinger get that thing tore apart and measure it.
