A lot of people say go with the chebby engine in your car but what you don't hear is the cost of all the other parts to install one of those ls engine in the car. You have to spend a bunch on the computer, the wiring , the new mounts, & then have it programed to work in your car. By the time you spend all the EXTRA money you can get a nice Pontiac engine in your Pontiac which is the correct engine in ANY Pontiac. If your going to put an engine that doesn't belong in your car why not go for a Ford engine they have cheap create engines to. Same amount of work & extra cost to put that in.
