M1 or Port-Matched LD4B on 408

Interesting that the LD4B could feed a stroker. Proof that It's a good manifold. And not ported just port matched?

He didn't write anything on my build sheet regarding the intake aside from "Edelbrock 4." IIRC, IMM specifically said they "Port-Matched" the intake because they ported the EQ Heads.
