the need for speed.

[old_is_new]

So I just got back from the track. Since there weren't any trucks other than the usual luvs and s-10's, I got to thinking about the newly aquired 68 short step my neighboor gave me. Any experience in builds for 8th mile? Im curious as to how much motor I need to push this thing into mid 6's low 7's. These trucks aren't as light as the heavies luv. Definately big block, and I want to stay n/a.
