I would think that with that weight a spragless would be very lazy. I put one in my 3200 lb Nova a while back and it only 60 footed 1.44 but ran 9.50's The plus was that it was ultra consistent. I swapped it out for a TCI off the shelf and went 1.33 60 foot with the wheels in the air and 9.30's It was like driving a different car. It will work, but its not ideal.
Hope this helps
