I know this is dumb and will probley regret asking it hear, but Is there anyway to increase compression without decking the heads or diff. pistons....maybe a thiner gasket? I am looking for more power with little money, I have already increased the timing to 15degrees with 93 octane, put a k&n filter in, and a catback, I have a offroad pipe on order. I don't know how much pulleys will gain you at the wheels but I know they are cheap (on that note do we need a balancer on our cranks, is there any pulleys that come with them or are all of them piggybacks) I am use to the 4.6liters that are alot differant from these motors. I plan on big power later with a top end kit (trick flow, or eldelbrock) but don't have alot of money now. I was also thinking about a bigger Maf sensor, throttle body with spacer (70mm), but I don't know how much power is to gain from these either. Any suggestions on where to start?
