SBC Block Weights (Dart Little-M & GM)
The Dart data-sheet lists 205 pounds with 4.00" bore for the Little-M Sportsman.
So, what does the Little-M sportsman 400 block weight with the 4.125" bore (should be a little lighter)?
And, what does the GM blocks; 400 (4.125" bore) and GM 350 (4.00" bore) w/ 4-bolt main block typically weight?
Thanks,
Warren

WJ,
Thanks for the GMPP link. It looks like a GM 350 is 181 pounds and their 400 is 196 pounds.
I called Dart and they said their 400 block (4.125") should be around 197 pounds. Basically 8 pounds lighter than their 350 (4.00" bore).
