Long-off 340 build

all the trouble your going thru to build a motor with aluminum heads, roller cam, etc, on a 340, I'm curious as to why not going with a 408 crate motor? May be money ahead with all the little stuff, like rockers, etc, and still have a warranty. Blueprint Engines BPC4083CT: Small Block Chrysler 408ci Stroker Base Engine 445HP/500TQ | JEGS
