If it's any help I got 590hp out of my 440 with a 6 barrel505 Stroker
No clue on power on this one except above 600.... and why I'm playing with the 6-pack manifold/flowing etc.,
we'll see power when I get it finished and on the Dyno, and where if time allows ? I'd really like to bolt an untouched 6-pack manifold back on for comparison.
