I like everything you're saying here. If $$ is a major concern I would consider 1 thing. What would it cost to get a 360 done and be quick enough to blow those haters doors off??? Versus...Expanding upon your 318 and being able to blow their doors off or simply just beat them in an 1/8th or 1/4 mile. That's why I was asking how fresh your 318 was. It sounds to me like you could make them eat their words with what you got under the hood right now. There are 318's running in the 9's. I don't know how many passes they can do between rebuilds but it can be done. However, You may just be wanting a 360 and the coolness factor that goes with it. I'm just trying to say that "financially" it may make more sense to expand on what you got. Only an ignorant person would bash a great engine like a 318. Mine is scary fast.
