alright thanks guys. i was looking at gearing, thinking about 4.10:1 cause that is what the lightnings have. Good idea? And what are some cheap differential options? I have been looking for some gt40 heads, but i only thought they were on the lightnings, so that should help alot with finding some. I'm thinking right now gt40 heads, long tube headers, and a cam. Plus maybe an intake manifold if i can find something cheap enough but worth putting on.
