Finally it runs like a proper car. Well not proper really (if a PT-Camaro can be called proper) but it behaves good. Drove it around the block to check if everything worked and nothing was leaking. Tried the new HydraTech booster and it brakes like hitting a wall. Did some adjustments on the proportioning valve to get it balanced.
One thing that is amazing even though the engine is a stock LS1 from a Camaro (except headers and no cats) it really moves. Gave it just a 3/4 throttle on 1st and 2nd gear and it pulled really hard.
I will take it out on the highway tomorow to make it perform some more but it feels really good and I don't regret the swap one second.
