A-1 8" converter?

I ran a 292/108 in my 367 at 11.3Scr with aluminum heads......and a clutch with 3.55s. I always thought the bottom was a little soft............But not thaaat soft.
I got rid of that cam pretty quick, cuz it wasn't right for my combo, and I wasn't willing to give up the 3.55s.
In my engine the power seemed to come on like a switch at close to 5000, and continued to 6500 real strong, still pulling at 7000. With my 2.66 low gear, that meant the power didn't start until 43mph, and finished at about 55, and decayed at 60.On paper that looked pretty good to me.In practice, the lack of lower rpm power, proved too much for me.
But as you might know, the problem wasn't so much the cam, as it was the lack of torque-multiplication, and the fact that the tires were directly linked to the crankshaft, so 30mph was 3500rpm.
Now you, on the otherhand, in first gear, will be running 3570 @30mph at zero-slip, so a stall like you are interested in, would be the Hot-Ticket to get past that soft zone. Still; in a mostly street car, 4800 to 5200 seems awfully high.
I think that cam power-peaked at about 5700 in my combo,(maybe a lil sooner) and that points to a 4200rpm torque peak.
I can tell you this; I used to hit the gas at 4000 in second gear,at about 47 mph,and she'd break the 295s loose. With your combo,47 would be 3310rpm at zero-slip,so a 4200 would probably get you similar results.To that end I'm liking the 4200.
But I don't run that combo anymore. My Barracuda is ~3450, plus driver.
