EFI SBC vs LS Motor

This is the first car/motor I've ever owned that's carbed. I need to start with having it tuned correctly, both the carb and the motor.
* Yes.


Have I decided LS or SBC? I'd really like to do LS, but again I have nothing against SBC. Have I decided 100% fuel injection? I suppose the answer is no. I have a friend that runs a carbed LS motor in his Panoz race car and that seems to run like a scolded monkey and cranks after 2 pumps of the gas EVERY time, mine doesn't even do that.
*Because this ...

Like I said previously also, 700hp isn't a must have. I'm not chasing a whp, a 1/4 time or anything like that. Someone had ask me a goal so that's what I threw out. More of a goal is reliability for the street, road course, autocross, than power numbers. I'd rather have 550whp and have it turn over 100% of the time I turn the key. I'd also rather not smell like exhaust/fuel every time I drive it haha!
* and this ...

are tuning issues.

All of my race engines fire easily after 2 pumps of the throttle.
