How much HP...again

About ten years ago I ran a new small block small less than 300 cid.on the dyno I made approximately 15 pulls on it most optimizing three different carbs, I tested a 600dp, 750dp and a 850 dp race carb off one of my 440s. I also tested the K&N stub stack on the 600 because it still retain the choke.

850 = 459 hp
750 = 455 hp
600 = 447 hp
600 with stub stack 453 hp. + 6 hp

I guess on the street 12 hp isn’t worth whatever drivability problems you might have with a large carb at least not one you would need to go out and buy. As to the K&N stub stack I spent a fair amount of time fitting it too the carb but I’ve been pleased with it’s performance.
