Compression ratio, how do you change it

Since the crank did need to be turned along with new pistons, and the need to have the piston swap done at the machine shop and probably rod sizing too, I priced out the rough cost of all that vs. a 440 source 440 to 512 kit. My numbers come out to be around $800 difference. So I put the old crank, rods and pistons back in my truck and made the decision to go with a stroker.

The bores will need to be cut .030 for sure. The rest of the block looks really good as per the machinist. His rough estimate for the machine work which is basic prep for rebuild, hot tank, crack check, and clearancing the block for the stroker, final fit of the pistons in the bores, assembling the pistons and rods, basically having it ready for me to assemble is $800.

This changes everything. Probably going to use a roller cam now too. Price goes up, just means it adds time to the build. The way I see it now, there are no Mopar big blocks in Heaven. Got to get it while I am here. :)
Sounds like a logical plan. Keep us posted.
