hey guy's does a LS1 have a speedo wire or is it cable? also what do the 98-00 usually dyno on avg with a 6-spd? is the `01 the year the put like LS6 heads or i'm not sure, thanks for any help.

 

There's a rectangular plug built into the cluster (about the size of a computer printer port) and when pushed into the dash it connects with the opposite end (there's no actual wire). This is the only connection to the cluster, at least on '99s.

01 is the first year of the LS6 intake manifold on the F-bodies and a M6 98-00 should dyno close to 300rwhp.
