LA 318 advice

Ok, how is milling the block wrong? If you’ve never been an actual machinist and engine builder explain your answer.
Well say he takes 0.100" off the deck any head upgrade down the line will need to be mill for the intake to fit, now you got an intake or head that only work's will blocks that been milled a 0.100". If you go through a bunch of upgrades could leave a lot of one off parts.
Plus your building power on stock pistons limiting future upgrade power capablies valve clearance etc..
Chrysler since at least the 1970’s has said to deck these blocks enough that on some of the pistons need to come out of the deck. How else do you do that? Make the piston longer? That’s dumb. It’s already too long.

I can’t understand why milling a block is the crime you all want it to be? Because an intake won’t fit?

If that’s the case you’re not an engine builder because at least 50% of the time the intake needs to be milked to fit.

Unless you are a hack and you slot the bolt holes. I don’t do **** like that.

If your only reason to not mill a block is that an intake won’t fit you need to get more experience.
Even so if it's just for intake, why would you rather a 0.100" milled stock piston block vs a block with decent aftermarket pistons and a cleanup mill job?
