Big Block Weight

[nivvy]

How much heavier is a big block than a small block

[Hot_Rodder]

Depending on which ones you're talking about, I'd guestimate roughly 300 pounds +/- It varies depending on what you're talking about, 318 LA versus 426 Race Hemi with the crossram intake.... or 360 with 4bbl, versus 383 4bbl...

340/440

Dont think its extremely accurate, but there are weights listed here:
