The only change was the msd wires. Previous best was 13.98 . First pass of the night nailed a 13.849 then the second pass some how dropped to a 13.434. Dont know what happend but not complaining. Now looking for the 13.3. Still need to put headers and some spray on and a stall. very happy with the ls1 considering all stock. still miss the lt1 though.

 

Very nice numbers.
