Also, how long were they ? Thanks, for your input .....

when first done i just had a short collector(cone) car sounded very responsive but didnt seam to have torque (60 foot wasnt there) removed the short cone and installed a longer tapered 10 " cone that opened to three inch and used the short cone removed and installed on the end coned back to 2 5/8 ,,,the car had its best 60' at the divisional in july,with not the best air conditions
but that is my combo,,i do a lot of asking of racers what they are running and there are so many different senarios for the same cubic inch ,,,gmonde
