Set up for 360/380 magnum crate engine

If you are looking for street fun, the 650 double pumper will be fine, however I would like to see a 750 vacuum secondary on this combination for the best power possible. The 727 will work with the manual valve body, but why? Are you going to race or street the car? Your shifter (stock) will be a bit of a problem, nothing you can't live with but, 1-3 shifts may occur. The 3.23 gear is a bit weak, but the 380hp will work with this fine. As far as the exhaust goes, 2.5 to 3" will work better and sound good as well. Again remember you can run what ever "you" feel you want, but it may not be very fast, just fun!
