What is a 408???

I’m thinking stock crank flattops with good rods and magnum heads.
Yeah it's fun cuz you can go in any direction. I've been thinking lately had I just got some Magnum Edelbrock heads intake and carburetor and just kept slapping them on 360 junkyard Magnum Motors I probably would have been doing just fine. There's a lot of different things you can do I do like the Stroker. It is fun building a kind of strong bottom end then you can just beat on it at will and know that it will never Flow enough to really hurt itself.
