Reaching your power goal ind of depends on whether or not you're talking about 800hp at the tires or 800hp at the crankshaft. 800hp at the crank is feasible with a 3.4L Whipple kit, but you would need to upgrade your internals and your stock hood won't fit, and lot of the power is going to be hugely dependent on who does your tuning, which will need to be done on a chassis dyno. Your best bet would be to call us directly at 1-877-578-2433 so we can get more specific about what you're trying to do and what you're going to need to make it happen.
