18 year old with Mopar project NEED ADVICE!!!

Hello everybody. This is my first post on this site so i hope it goes well. Just some unnecessary information about myself. I am a 18 year old senior at Jefferson High school in Monroe, Michigan. My auto shop teacher, Rob Eppler, is a very well know gear head and racer around southeast Michigan. He has been guiding me in the world of automobiles and has been doing a mighty fine job. Last year he gave me the opportunity to drive and race our 1971 Dodge Demon, powered by a naturally aspirated 360 and backed by a 904 transmission. My best ET was 118 mph @ 11.58 in the qt and that's only starting out in second gear! Anyways getting back on track, sense I was a little kid my father has always had Mopar's. Growing up around it I said "Hey! I want one." Being 18 now, I have owned 3 Rams but never a old Mopar muscle car. Now I am purchasing a 1973 Dodge Dart Sport in the spring and its already a done deal. It is just a bare body but already set up for drag racing, that's exactly what i want too. I'm looking to build just a strip car, not a pro street. The body is solid and no dents or dings. My vision for the car is to run in the mid to low 10's. I haven't made up my decision about the power plant yet, that's where I was hoping I could get some help. I know I don't want any power adders, just all motor. From what I've researched, most of the rest of the car's components depends on that decision from tubular K-member, rear axle, drive train, etc. I wouldn't mind a 360 but I don't think it has enough power to get me into the ET's I want. Anyways let me know if I'm missing any key information. I will get some pictures up of the car soon. Thank you guys very much!
I'd BIG BLOCK IT!You won't regret it..
