The LS3 crate engine is an iteration of the V8 that boasts ... The extra-powerful LS376/525 hits a loftier sum of $11,289.50, while the LS3 long block variation is $6,195.70.
There is a downside with that approach, though: the LS376/525 is a crate engine built in a factory by experienced workers. It also comes with a warranty, offering peace of mind to potential owners.
