71 440 or 74 360?

so i can get those numbers even thou the 360 is a 74 block? awesome!!! i thought being a block when emissions kicked in after 72 would hurt my chances of make a monster out of this 360

The problem in emission engines lies mostly in the piston and its pin height affecting the compression ratio...new pistons and maybe some head milling will bring it up into the workable 9-10:1 range...
but ya, all the boys will say "no replacement for displacement...go with the 440"...
