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.

If you peel off the LS heads what you have left is just a short block. Not the same but a 318 block can handle 500 horse easy enough. The LS's are like the Gen 3 Hemi with the cross bolts and the like. Very strong indeed. Yes they can handle 1000 horse.
