I ran a 750 Speed Demon and RPM intake on my old Vortec 350. I run the same carb on my current motor but since I no longer use Vortec heads I run a Professional Products hurricane.
I'm also a huge fan of locking out the timing on just about any car with an aftermarket cam. In my experience it always makes the car idle better, run smoother, and go faster at the track. I have a 10.8:1 SCR motor with a CVR mini-starter and crappy walmart battery and it starts just fine without any sort of start delay even on the hottest of days.
