The motor I am thinking of adding to my c-3 has alot of cam. How much vaccum is rewuired to run the brake booster and the headlights? In the future I will most likely swap to a hydroboost MC and no-flip up headlights, but i don't want to have to do it to get this engine in. Snakeater

If the HL system is tight it will operate on 5".

Ol' Red has enough cam it only makes 12-13" of vacuum. Headlights are a tad slower than they could be, never had any noticeable problem with the brakes. It's also got that big vacuum tank on the left side. Assuming it's still plumbed in (I haven't looked) the slow headlights may be the fact all the parts are the originals.

Mine carries 7" at idle,headlights and brakes work just fine.
