"big boy" shortboard

So I just got this cheap board. Pic in thread here: https://surfing-waves.com/forum/viewtopic.php?f=20&t=20486
Performance wise, due to my lack of repair experience and the several dings I filled pretty roughly, probably it won't shine.
It's 7'4" long, I'm in the North East and pretty much all my surfing experience is riding my 7'9" BIC funboard.
This seems to me like a shortboard built for a big guy. I'm 5'8" and 160 lbs. What can I expect (not taken it out yet, need to add fins)? Any tips on handling this board?
