Small Block & Big Block Chevy Specific - Weight of LS1

I was wondering how much does an ls1 and 6 speed transmission weigh.
Also if anyone knows, how much does a 13b-rew with the manual transmission weigh?

what the heck is a 13b-rew??????

13b is the mazda rotary.

LS6 crate motor is 382 no clutch, 420 with. T56 is 125. 5#s under the UPS limit ;)

Thats about 5 pounds heavy because of the crate.

GM claims the fully dressed LS1 is 497lbs.

Havent seen any weight figures for the 13B, but the 20b is supposedly over 700lbs.

Too be exact about this~a LS1 engine weighes 525lbs,the trans will weigh 180lbs there abouts! Hope that helps ya! :)

382 makes more since because im trying to compare the weight of my big block to my ls1 the big block all iron is 650 so it doesnt make since to me for an all aluminum small block to be 125lb. less

I do remember the ford 5.0 was supposed to be 50 lbs heavier then the n/a 13b in the fc rx7. And im sure the twin turbo setup adds quite a bit of weight and the ls1 should weight less than a 5.0. If your looking at weight balance i believe it's pretty close to 50/50 w/ an ls1 swap (i think it said something about that on the hinson website). Atleast thats what i remember...but it's been a while since i looked into the whole v8 rx-7 thing.

ls1 is less than half of a bbc, trust me. i have ls1's, sbc's and, bbc's and the ls1 is by far the lightest.

A 6.0 out of a truck weights more than a 350 sbc if both have cast iron heads.
