Drive train help

Hi, I am in the process of building a gen 6 454 from my old work truck. That truck had a turbo 400 and a GM 14 bolt rear with 4.10 gears. My new frame came with an Eaton HO52 and I'm not sure what gears are in it but from everything I've read the most common gear size was 4.57. My question is, with the 4.10 gears and turbo 400 my old truck would cruise 70 mph at 2,300-2,500 rpm. If I get a set of 4.10 gears for the HO52 and put the same big block in the truck after building it (yes I know it will never cruise that low again after taking the rear wheel HP from 290 to 500) what would be a good 4 speed or 5 speed transmission to use for good take offs good quarter mile times (not looking for 10's just a respectable number for a pickup) and good streetability. M22, NV4500, etc etc etc. I'm still new to figuring out transmissions as I've not learned as much about them as I have about engines. Any help would be greatly appreciated. I don't want to buy the wrong transmission for the truck only to find it out once it's on the road.

Thanks,
Stephen
