Hey guys I was wondering if anyone knows what the weight difference (if any) between a stock 2004 Silverado 5.3 engine and a stock 1976 Camaro 350 engine?

Thanks!

I think I found it, if anyone wants to correct me

Old school chevy 575 lbs

New engine 520 lbs

According to my research between 20 and 45 lbs depending on who quotes the numbers. The aluminum engines are supposed to be around 100 lbs lighter than the GEN I / II, again depending on who quotes the numbers.

I don't know if that is fully dressed with all accessories, iron or aluminum heads, bare engine, full of oil and water and ready to run or with complete electronics, etc.. Too bad my bathroom scale isn't large enough to hold one so I really can't verify.

I have also seen shipping weights quoted all over the place but that isn't very useful either.

This is all I could find also

Complete LS1 – 430lbs
Complete iron block 6.0 – 518lbs
Complete Gen I/II – 531lbs
LS1 bare aluminum block – 103 lbs

i would imagine more than 18 pound weight savings from an iron headed gen 1 motor to an aluminum headed gen 3 though
