440 build for a tow rig/"muscle" truck?

Alright well last Sunday I drilled out the oil passages, pretty easy I just had to be careful at the beginning of each hole to make sure the bit didn't grab the wrong part of iron. Took maybe 20 minutes tops, probably wasn't necessary but for the time and money invested there's really no reason not to.

Yesterday I dropped the block (with main caps and bolts) and crank to the machine shop but the owner asked if I had gotten pistons yet... I said no, hadn't figured out which type or oversize I need but then he said he won't try to bore and hone the block without having a piston to size it to. Makes a lot of sense actually. I'm gonna call him on Monday to see what kind of overbore size he recommends, I'm guessing .030" over should do the job since the bores have a noticeable ridge but I'll wait to order pistons until I confirm with him. I did find Icon pistons that I think will put my compression ratio where I want it and aren't super ultra heavy like the repro TRW forgings, price is also good it's just about the same as KB hypers (I know they are made by the same company)...
