No replacement for displacement!
My 493 is just shy of 9:1 and made 600 ft/lbs at 4000. It was making 500 ft/lbs by 2000 RPM. MP509 cam, TBI and Edelbrock RPM heads with 1.7 rockers. That's the magic of cubes. That cam in a 440 is a stone off idle.
It's happy on all but the hottest days on 87 regular and if my timing curve was a little less aggressive, it would likely be OK on 87 all the time.

Sounds awesome! I am looking at cams one step milder than the 509 but I’m not buying a cam until I finish collecting a lot more parts.
Does all that torque move a factory high stall type converter up a few hundred rpm? What are you running for a converter?
Pretty sure it's a 2800 stall. It's a Turbo Action that I got at Mancini's.
The first time I tried to check the stall it ripped the left motormount apart about the time the tach approached 2400. I put in a set of Polylock Schumacher mounts which it stretched but the brakes would never hold it and it didn't have enough traction to get a flash stall reading either.
The car was a 66 New Yorker, 4800 lbs.
