Hey, I also seen somewhere that it weighs 525 lbs but I believe thats the entire motor. Im just looking to the block weight. Do you think the w/h/l is just the block or the entire motor?

 

entire motor the block is only about 25#'s more than a 302

 

Well than do you know how much a 302 weighs?

BTW, I am trying to get all of this information because I need to contact USPS about shipping prices and I need to know the weight and dimensions.

 

rough guess? 165#'s. i can lift one no problem

 

14 h 18 w 12 l give or take

 

^^ Awsome, thanks alot.

Jasperstang.... I will get back to you!
