Is the stock cast-iron 351c 4V intake manifold good up to 6500 rpms?  The following article says so, but tons of people on this forum say 5500 rpm max.  Who's right?

yes, this article has numbers for the supercharger too, but below is stock intake with XE284H camshaft and headers.

351C produced 447 hp at 6,400 rpm and 411 lb-ft of torque at 5,200

Thanks.
Jim
