I have a 78 malibu that I just put together it has a 383 small block with a th350 trans with a TCI street fighter convetor 241001 and a 9 inch with 410 gears and 2756015 et streets. My 60 ft was 1.7-1.8 all night I felt like the car just wasn't leaving hard. I line it up foot on the brake it stalls at 2400-2500 then when the light turns green I floor it. I am a master tech but new at racing am I doing something wrong? How can I improve my launch?
