Help me win this argument 400 in a 72.

i vote for the 400. its a no brain, bolt in affair. its gonna cost you a chunk of change no matter what you do. in the end the 400 is gonna build more power, and yes I know what it takes to build one.

you just cant beat the WOW factor and the low end grunt of a big block. it even sounds more impressive to say you have a dart with a big block in it.
