Sounds like a tune issue... A good tuner can make a big cam drive just fine w/out stalling, dying, or surging.
You won't put down 450 cam only. Throw a nice set of heads on it, and you'll get a lot more power out of it.

You mean make it look like you have more power than you really do? Or just improve your current setup with a much better tune. Where are you taking it to get tuned?

Check the stickies in this section for heads and valvetrain. There is a TON of info in them that will really help you pinpoint what you are wanting to achieve with this car.

Orangepeel said it best. For heads, call TSP, they can set you up w/ something to perfectly match that MS3.

Personally, I would run a 243 from TSP. They will spend time talking to you about what you are wanting to do and the goals you have for the car. TSP is good people.
