Hey guys does anyone know the weight of a complete stock 6.0 with aluminum heads? engine only. Also the weight of a complete 5.7 aluminum engine with heads on it? Thanks folks for the help

 

Iron = 90#s heavier if i remember right

 

Yei think it is somewhere between 90-100lbs, But I dont know what the LS1 wieghs.

 

I weighed my 2001 LS1 long block against my 2003 LQ4 long block, don't recall the numbers, but the difference was only 65lbs. I was expecting 80lbs or more, as often posted here, maybe the 6.0L with iron heads would weigh 100lbs more.

 

The most common number I've seen is that a bare iron block weighs ~75lbs more than a bare alum block. I've got a bare iron block in the garage, but I'm way too lazy to go weigh it.

 

all i know is i picked my short block up by myself and that was pretty hard for me lol and im no average joe haha

 

Our LQ9 long block motors weigh a tad over 500 pounds, the aluminum motors weigh in at 385. Keep in mind these motors include forged parts so it might be a little different then stock but not far off.

 

Cool thanks alot man

 

Great info!! I had always heard 75#'s but that really makes a diff on streetcar you want to handle well.I will for sure go aluminum on my rebuild the question will be can I afford a 402 or will it be a 383. Can't go wrong either way
