Here's some basic mods to a stock LA and Magnum short blocks
In stock form the magnum makes more stock hp and seems to respond a bit better to basic cam 4bbl headers but were only talking like 20 hp or so. Is that worth a swap? It's a bit from CR but mainly do to heads, LA will accept magnum heads but also a little work to the LA heads will also work or better yet a set of speedmasters etc.. if more than basic hot rodding will do.
