521 a429s. 1st past off the trailer car had a 1.38 60ft and a 4.09 330 ft. and started spinning so i let off. 2nd pass had a 1.40 60ft and and 4.11 330ft spinning and went a 6.28 1/8 mile and let off at the 1/8 and coasted to a 10.01 1/4 because i did not know they had the 1/4 clocks on for our lane. would have went in the nines easy. it bust the bypass hose so i could not make another pass. this is only the 4th and best pass on my new 521. the first 2 were last sat. and the car would not accell because the hood was too close to the vent tube on the carb. i think this car can 5.99 with more gear and put the hvh 1" back on with a new hood. the carb is sitting on the intake with no spacer right now. play with timing and loose some more weight out of the car. 3265 with me in it 3.73 gear and a glide and 34 timing. im happy so far but i know it car do better. slick are old and was spinning on take off. leaving at 3800 on the break. oh yeah all on muscle. no gas. almost as fast as my old 466 on a 210 shot. thanks to all the guys on the site who gave good info.
