Re: LSx

More or less

The engine itself is very cheap, but the necessary Fbody parts that come free with an alum 5.7 are not cheap, so the total package is generally the same or a bit higher

Also factored in are the people fab alot of the parts themselves so the cost is significantly lower, compared to the people who "only want to do this once" and mod the crap out of the engine with the swap, so the cost is higher
