Re: Please help me!!!!!!! : (
To get 550 HP N/A you will be on the ragged edge of every spec. You'll need as much compression as you can possibly get and still use pump gas. You will probably need a solid roller cam but you might be able to get there with a hydraulic roller. Also, you will need the best aftermarket heads you can get....GM stuff won't get it.
Are you sure you really need that much HP? 450-500 will be pretty easy in comparison. JMHO
