I am currently tossing around the thought of using the stock stroke 3.58 inch 12:1 domed pistons and putting them on a 3.79 inch stroke crank to do a HUGE bump in compression.... talking like north of 14:1 maybe even 15:1 compression.
Using a 3.58" stroke piston on a 3.79 stroke crank will move the piston up 0.10" in the bore when using the same rod on each crank. Approximate piston compression heights for each piston for these strokes is below for off the shelf pistons.
Once you have your block checked at a shop for where the deck height can end up you will be able to make your decision as you will know where the piston will end up in the bore and how close the dome will come to the W2 head model you intend to run.
As mentioned earlier if you have the funds and have the information from the shop on where your deck height can end up being, you could source a custom piston for your rod and crank combination as well as speck the dome and ring pack to best suite the heads and type of use you will be subjecting the truck to. Aftermarket pistons will also be a good bit lighter and be result in less stress on the engine and rev up a little faster.
