Okay, here is what I would do.
1. Get a high rise hood
2. Order a small/medium sized blower
3. Get a good carb to feed it, headers, and nice mufflers
4. Get the VB&P performance plus suspension package
5. Possibly leave the rear gear alone, as it may already be good to run with a good solid street blower.
A blower will also work great with your auto trans.
Down the road, when/if you eventually wear out the engine, you can then upgrade and shoot for 500-600 hp.
The Jap cars won't know what hit them when you pull up with the blower under the hood whinning and screaming. It will sound like a jet air plane going for lift off when you throttle into it.
You will have all of them wishing they had an American V8 shoehorned between their front drive axles.
Plus, a basic blower kit is cheaper than a long block replacement, and will yield more power, looks, and bragging rights.
