I love how people always cry about the weight of big blocks. There's only about 150 pounds difference between a 360 and a 440. The 383 has a 4.250 bore. Say that ten times. Maybe it'll sink in. If not, you need help.
People will go on endlessly over the cid and bore difference between a 318 and 340/360 but an extra 23-43 cid plus a 1/4" bore waste of time. Funny how no replacement for displacement/bore ends at 360/408.
If you don't mind a square engine you could be running around with 496 instead of 408.
