First off....there weren't many 451 low decks around (only in magazines) back then but.....I had a 383 rod 451 Low deck back in early 91's, home ported big valve 452's, Venolia zero deck flat tops, A Lunati 30307 520/547 lift 240/250 @ .050 duration with an M1/worked 830 Annular and 2" Pro-parts headers mated to Flowmaster 4-2-1's phased at 180. It had a 10" Fairbanks that stalled around 3400 and a 3.91 8 3/4 with McCreary Dirt Track tires. It was in a 73 duster and it ran high 6's in the 1/8th at about 100-101. Really quick for it's day as a street car and for what it was.

I had a Weiand Team G on it to try and it dropped off like 3/10ths, tossed that boat anchor in the drink. Thing wouldn't fall out of a tree with that manifold on it.
