So after being out of commission since May 2010, I finally got my Grand Prix running again three weeks ago. I got tired of getting the run around from the shop that has the 305 for it (been there since April 23rd of this year), so I decided to go to Plan B and pull the 350 out of the Monte Carlo and put it in the Grand Prix. I got help from a friend of mine, who went through the engine and cleaned the pistons, lifer valley and valves, put on a new timing set and all new gaskets and seals. I cleaned and painted the engine (GM Blue) and we got it in the car. Fired it with open headers, he fabbed up a new 2.5-inch y-pipe, used one of the Monte's Magnaflow high-flow cats, instead of the stock crap, to connect the headers to the stock single cat-back exhaust (cat-back duals coming with next years tax return). I finally got it tagged and been driving it for almost three weeks and it runs great. The Monte will be placed into storage and will receive an eventual restoration (I'm also thinkin' its big block time).
