The 741 is greatly underestimated. I have run them behind 440's in A-bodies and B-bodies. My 67 Belvedere ran a .040 over, 10-1, 440, 452 heads with a mild bowl porting, M.P. 280 degree .474 lift cam, Weiand Action Plus intake, HP exhaust manifolds, and a 2800 stall convertor. With that small cam it had an abundance of torque. Ran 12.95 at 108 mph. 3.91 Sure-grip with 245/60-15 tires. Ran it hard at the track and on the street. Never a problem with the 741. Might have been different had I run slicks at the strip. It's STILL better than a 9 inch Ford!
