can a 440 be installed from underneath?

thank you all, that will save me so much time and effort when I go to install it. I had a 72 duster that I put a 440 in when I was 17 and I installed it from the top. that was 43 years ago but I still remember it was a pain to do. Especially since back then the only headers available were fenderwell and it was my everyday driver. This will also be a street car but not my everyday driver.
