Performance Questions 225 vs. 360

The OP'er main question should he spend $1000-$1500 dropping in a 360/5.9 or could he spent that money on a go fast parts for the /6 and would it get him in the 360 power range. There 3 low K 5.9 in my area for around $500 that leave $1000 to install it and have 280-320 hp on tap (depending on Headers or manifolds), the 5.9 in my Cherokee
Is fast in a A-Body that weighs 1000lbs less should be a rocket more than enough and be streetable sure a turbos /6 is an option but really dollar for dollar a low K running 5.9 is the best bang for the buck.
