IMO - you should try to figure out what your end game might be - or at least have a good idea. If money is no object (and you want around 700+), and you might not mind paying money to almost do the same thing twice, then what CW' suggests is solid. But - the stock cam is going to limit you on fuel/power. If you know you want more, it might be best to skip anything to do with the stock blower, and just go with a cam, maybe a low-side, and 2650. You could skip the 2650 and still do a cam, but you'll still be limited by heat from the 1740. E' will help with that, but you'll need more fuel, and blah blah blah

There are too many ways and opinions to skin this cat.
