As I shared on FABO, I think your best bet is an edelbrock headed stock stroke 360. This will help you hook, you'll spend your money on something that both increases performance of the engine (better flowing heads) and also makes the front end significantly lighter. You can keep the costs down but I would suggest swapping the edelbrock standard springs out for some beehive ones (they are SBC sizes so it's cake). Get some light hypereutectic pistons that get it to zero deck and I would invest in a hydraulic roller in the high 220's duration at .050 and it will really rock.

My car is pretty fast and you can actually put the power down pretty well on the 275's.
