340 vs 440

If both are "hooked up" and built alike, the bigger motor hands down, if the 440 is spinning , the 340 will kick its a$$, have less cooling problems , maintenance problems, and handle better .
Which one is more impressive --------------?
I know a young guy here in town that has a big? 340 in a 68 barracuda that will kick my 505" 68 barracudas *** > guess which one is hooked up !!
