How many street driven high 11 second 318’s do you see? I haven’t seen many. Apparently the 400 HP 318 is the new 500 HP 350 chevy. You make make it sound like a rebuilt core will make 400. Ain’t no way. Have you ever built a 400 HP anything.
It's a pretty well known fact stock magnum heads with some valve springs will support 400hp. With the smaller bore and port velocities on a 5.2 magnum those heads are capable of making 400hp on a 318. Just because it's not the norm doesn't mean it's not possible.
People that have no understanding of volumetric efficiencies are the ones that are talking out the wrong end. 65 cubic inch 4 cylinders are putting out close to 200hp out of the factory naturally aspirated.
Another one of those cheap fools acting like a high schooler and won't put a aluminum block hemi together. Keeps cobbling up those $8,000 small blocks
