Big horsepower 318 builds

The LS 4.8l and 5.3l is probably the most popular swaps out there, putting out 400-500 hp nobody is like can't be done these are only exotic crazy unstreetable race engines.

The only thing that makes those engine specials like the new Hemi's is the heads flow numbers that before only came with specialty aftermarket heads before those engine were produced. No reason you can't build a 5.2L like a 5.3l LS and have similar results.
