Are GMPP crate engine weights correct?
Im reading the 2014 catalog (pgs 64, 65) and finding good old sbc crate engines w/alum heads weight less than the all alum LS3 crate motors! But i seem find a lot numerical typo errors so dont know what to think. Now I need get the 2015 catalog ASAP.
But what i see now is the LS3's (3 variations) all weight 415lbs and the ZZ383 weights 410lbs! Turnkey ZZ5 = 410lbs. Odly the ZZ4 turkey is a fat 511lbs (cant explain that). Also the 7 liter LS7 weights 440lbs!
Is someone in the GMPP print room dyslectic?

But for the ZZ383, ZZ5 there's no way they're that light. They're probably right around the ZZ4.
If you look just above the turnkey ZZ5, the chart claims the base ZZ5 weighes 510 lbs.
I'm sure someone went typo crazy or had some cut and paste errors. The turnkey ZZ5 has AC, power steering, alternator, acc'y brackets, ignition carb and intake. I'd guess that *this* is the 510lb variant.
The LS3 has front accessories, headers ignition and throttle body. So not quite apples and apples.
At the very least - I'd say they are not correct.
