The trap of the industrial / motorhome 318-3

Those low compression height truck pistons may be able to be used on a turned down 360 crank for a cheap stroker in a 318. The standard 318 pistons are only .040 proud of the deck using a 3.58 360 crank? Someone do the math for me, I'm on my phone....iirc the 65 closed chamber 273 heads were blueprint 57cc..?
