I think the selection of parts is all dependent on what you intend on doing with the car. There are any number of good cranks, cams, heads and valve train that you can build a reliable engine with. My 408 lasted for several years without hurting it. If you intend on spraying it TUNE is EVERYTHING !!!!

well trick flow period. but your bore size in the minimum required for the 235. with a putting a 225 on it you will floe just a little more air than you can with a 235. the number you see flow wise. with a 225 is done with a 4.0 bore. so with just a little larger bore you can actually flow more through the head than shown. the flow number you will see on a 235 is a 4.125 bore. so running the smaller cc will help you in the end.

go to trick flows web site.

go to search type in

ls2 225 then click on one of the listing go to the bottom the is a link to a flow chart

then search

lsx 235 and repeat and there you can see what i am talking about in more detail.
