I too am seeking advice in another post, it kind of sucks and it's kind of fun being at the low end of the learning curve. It sucks not knowing, but learning about this stuff is a blast!!!
I spoke to people at PTC and TCI, both companies were very helpful. I make it a point to tell them that I know very little.
They need to know things like, Cam Specs, Tire size, car weight, motor size, ect......
Let us know what you end up with, GOOD LUCK!!
