SBC or LS Style?
The sbc has way more options, but the LS comes out swinging way harder stock. 15 degree heads and the crappiest 4.8 with a carb conversion and headers you break 300 hp. And that's a punk truck engine. Lol

That's one sweet looking engine! If you're restricted by a budget (as most 16 years olds are), go with the SBC for right now, but ditch the Eagle crank. Sell the Eagle crank on Craig's List and apply the money towards a forged unit.
A few years ago, I would have recommended Scat, but their quality control now leaves a lot to be desired IHMO. Even an used, forged factory unit would be better. Whatever you buy, be sure to mic out the new crank or have a competent machine shop do it for you. (A high RPM busted crank will take out an engine quick!)
Once your budget allows, sell the SBC and buy an LS series engine. New learning curve, but great little engines. Junkyards are your friends especially the "you-pull" type.
Whatever you do, have fun!

Eagle makes a fine product, the op didnt specify which Eagle crake he has. it could already be a forged piece. Man Id stick with what you have already. you car being a LT1 car the sbc will bolt in, plus you already have it. i would change the pistons though and go with some SRP pistons, then you can have some real fun. I like both style motors, they both have their strong points but since you already have this setup then go ahead and use it instead of starting all over. trust me you can get a SBC to run pretty damn hard. the SBC in my mustang should put it in the mid 9 second range and its a pump gas motor (10.2:1 compression) I can get races all the time cause for some reason people think that since its an old school SBC that it cant run as good as an LSX motor. I love proving them wrong.
If for some reason you change the rotating assembly (rot. ***.) look into Ohio Crankshafts. They make a great product and they are fair on their prices. I would recommend the "383 Street Rodder Small Block Chevy" kit. I have the "383/406 Small Block Chevy Super Kit" in my motor and have had hundreds of nitrous bottle through it. my 385 SBC has about 15K hard miles on it and its still goin.
