Obviously I'm going to need a new block/head, I've been talking to someone on here that is willing to sell me a block/head for $250 + shipping out of PA (Needs machined and internals I believe), any input on if this is worth it? What parts should I be looking at as far as internals go if I'm wanting to push between 400-500 HP? Also how hard/costly is it to go AWD on my GST? Just thinking , probably not going to happen, but if it isn't TOO much of an expense, then who knows. (Keep in mind, I'm gonna be trying to piece stuff together over time, I have nowhere near the budget to buy everything all at once unfortunately, which is why it has already been parked for over a year ) Thanks guys!
