That was only 461 cubes, that made 600hp, and 575 tq. Thats 1 story, there are others. With 582 inches, and monster tq, my guess, would be somewhere over 750+ ft/lbs at fairly low rpm, 4500, somewhere in there, with the above combo, in that chassis, it will be hairy. If that sounds fun, than do it, but, just be careful is all I am saying.
Very true.
Here is another one.
I built a customer a 505 and used his junk pro comp heads. After putting in seats, some weld in the chambers, and port work, they ended up about 370cc and went 380-390cfm with a 2.300 valve. 10.5:1 compression. custom 262 274 @ .050 on a 110 with .720" with jesel 1.75 rockers. Edelbrock port matched super victor with a 1050 holley.
Made 742 hp @ 6900. The man just KNEW he needed 700hp. Now he rides around and wastes about 200 on the street. Has good response and drives good, just too much for a street car without good suspension. Wheel hops at 80mph.
But if your after big power, im with curtis. Go big with it.
I have done a few others with bigger cams, but this one drives the best. More dangerous also though!
