we've got a 36-1 trigger wheels setup that integrates with our serpentine belt kit. then top that off with a cam sensor bushing and run a jeep cam position sensor on the big block. then you can run whatever ecu you want. i'm still a big fan of the megasquirt setups. you can get their gold box thats preassembled and fully tunable. goody has had good luck with his, plus theres a ton of features on the box you may or may not need. tuning your going to want to have it on a dyno anyway. you can tune the megasquirt kit with tons of support from online forums, the megasquirt also has datalogging capability, you can record your tables and then run them through an iterator which will tell you what to adjust, tweak the tables and drive again. rinse repeat. maybe a little more tedious than the self learning systems but this is basically what the self learning systems do. you just dont see it.
