Going by memory, I think Ed's running about 125 mph at about 3900 to 4000lb in good air. You can figure hp from there. Moroso calls it about 590 net flywheel. The fact is that running nearly 10s @ 125 on manifolds is impressive to say the least. The 125 mph makes it clear that the exhaust manifolds can support a lot of power. I don't know if Ed's intake manifold is ported, but others have gone over 120 with unported intakes for sure.
