Yeah hello Eli, sorry for taking so long to get back to you the engine as far I know is standard as this is the way that I bourght it from the wrecking yard. Gave it a degrease and paint put a Burton rocker cover on it and put it in.Unigroup Engineering told me it is the best standard 2lt that they have had on their dyno. It revved to 6200rpm but power dipped @5800.A significan't incrase of power was made just by usind 98 octane fuel and running a 3.45diff ratio.
