i dont typically recomend Comp cams but these would be a decent fit.
they will have a little lobe, not a lot.
i dont hear you saying that you are changing you gears, stall... so you can't go with a cam that has a bunch of lope, everything has to go together. if you want a loppy cam you will need shorter gears (larger numerically) and a higher stall. and i have mentioned this before, buying a torque converter with a stall speed less than 2800 is pointless in my opinion. if you are willing to spend the money to put in a 2800-3200 stall and put in a set of 3.73-4.10 gears then i would say you could go with a higher duration cam but if not, you will need to stick with a cam in the 260 maybe 270 range, and for a hyd flat tappet cam i wouldn't use one that had to much than 50° between the advertised and @ .050 durations. i know that the first cam i posted does but it also has a lower lift which brings the ramp rate down.
