Quote: Pretty simple to get 400 HP out of your 440, should be no need for a crate engine. If the engine is fresh just put a good dual plane aluminum intake under your 770 carb, install some headers and good free flowing dual exhaust, good ignition system and you should be pretty close to 400 with maybe a little extra, good luck.
I'll also add call a cam grinder and have one made for your application. There are a few guys that make good cams for the low compression engines.
