Weights of LS Blocks
I also have more data from some other parts I've weighed so I can update the chart.
Since converting my car from carbureted LT1 to EFI LS1 I lost a total of 45 pounds.

Don't know how I've never seen this thread but it's a nice wake up call for all the people on tech who keep spouting off the weight difference is LESS than 80lbs between ls1 and lq4/lq9. It's actually a bit more.
The hard part to swallow about this weight is its front end, where weightloss is most important, if it was in the rear I wouldn't mind a bit but looking into future strokers this makes an LS2/3 worth the money maybe. I don't want my 60' taking a **** at the already less than impressive track prep my local track has.
So does anybody have an accurate weight for a 6.0 iron block alum head motor complete less power steering and ac compressor? I'd like to know just busted a alum block cracked around the motor mount bolts but it las test 5 years! Thinkn about going to steel block for durability and better ring seal and hopefully not to crack it around motor mount bolts!

Where are you getting blocks that cheap. I just gave $350 to have a crack welded and sleeve put in an LS1. Cheapest I can find an iron 6.0 is $1200 complete, $700 long block with iron heads and LS2 is $1200 bare.
I'll give $800 for a bare LS2 right now. Who wants my money?

Weight on the front end can be reduced to help compensate for the added weight of the iron block. Putting the battery to the back can save around 40 lbs and help with traction. Changing out some front end parts can save you another 10 - 20 lbs. I'm putting a Dart LS iron next block in my C5, the block weighs 227 lbs. and can handle high boost. The oiling system has been redesigned to give you better oiling than the LS1 blocks. Personally the oiling system and added strength sold me on the Dart block.
