a frien has a corvair engine in his VW van. He is wondering about installing a 4 barrel intake and carb for both increased power when necessary and also increased fuel milage. Can anyone recommend for or against the carb change? Any remarks would be appreciated.

Best bang for the buck? Stock carbs.....

Centermount 2 or 4 barrels have slow/low end issues. They are so far from the heads that there is a hesitation issue. Along with icing issue in colder climates. About the only good application for the centermount is for high speed racing, even than most convert to Weber carbs.

This is actually something I have some personal experience with. I had a 65 Monza with 4 single barrels that were just completely shot. I saw Clarks had a complete centermount 4-barrel set-up for sale used with a Holley 390 cfm and all the linkage. I went ahead and got it and put it on. The car already had an electric fuel pump. Once I got the carb jetted properly the car ran great. Excellent throttle response and much more power. Gas mileage did drop a fair amount, but part of that could have been my foot. There was one major drawback to this set-up, though. Once the ambient temperature dropped into say the high 40's, the 4 chrome tubes would begin to ice up and the drivability would turn to crap. If it was damp too, you might as well forget it. Barely drivable. But in warm weather it worked great, ran like a champ.
