built up 318 oddly low MPG's? hp rating?

Ya i probably wont be really messing with the engine, i'm only 17 and have been building it for 16 months haha heck I want to drive it now before I got to college in 6 months. Any money I could put into this engine will go to a 360 stroked to a 408 someday, I only built up this one because the bottom end was already done.

I agree with the MSD stance, everyone seems to have one but I hear they dont add a whole lot, but if my ignition craps out on my again i'll just put the money into the MSD.

Could be i am also letting the engine warm a little too long and my electronic choke isn't set quite right and it idles up to a healthy 1800 haha I think i'll set it down to 1200 and let it only warm up a min before driving it, they are cast iron heads so I can't to a lot of harm there if I grandma the car in the mornings.
