318 engine build help

That is huge power for a 318. Not to say that it can't be done, but its not going to come cheaply or easily!

Based on the numbers I've seen if you want to stay streetable I would say you'd need to lower those expectations into the 400 hp range, unless you're planning on running forced induction or a lot of nitrous.

What's the info on the car? Is this a race only deal, or something that will could see the street? And if you really need to get to the 600hp mark, why a 318?
