WTB inexpensive complete 360 engine

I have a 340 now I want something I can learn on and increase HP with the current motor still in the car. Car runs fine now dyno'ed at 227 at the wheels. Wish I could build a 408 stroker but money won't allow that to happen.

Thanks any way but the 318 is not what I'm looking for. Good luck finding a home for it.......
