5.90 in the 1/8th is about 9.23 in the 1/4 and at 3000 race weight will take about 750 hp. So i would definately find a good 400 block and go with a 512 with ported large port heads. The easeist route is 14.5 + compression, mechanicl fuel injection, alcohol and a rollercam similar to an Isky RR735. Plan your valvetrain carefully. I needed more spring than isky called for with that cam. You might hit the number at 3000 lbs with that recipe and bowl porting only, but it will be close. I went 9.34 at 143 mph in Minnesota (1800 da?) With bowl ported 440-1 heads, 13/1, 499 cubes, 283/290/110 roller cam of .760 lift. Alky injected, shifting 6800.
