RAC1812, three carbs and headers are not a sure bet for more horsepower. I installed three carbs and header on my 250. I ran great, started good, and got decent fuel milage. I took it to the drag strip for some fun and testing. The next week I went back with the stock intake and exhaust with a good running stock Monojet one barrle carb. The stock set up was quicker by .02 seconds and the three carbs were faster by 1/2 mph. I now run the stock set up full time. Joe
