darn good machine work and a heck of a ride, whats the cam specs?with a 4.10 that is very impressive, would love to what it will do with a 456 or 488 gear. nice ride, flat tops produce the most power as long as ya can get the compression up there,im converting a 71 dart to street ,just waiting on the pipes and mufflers, with a 0.55 over runs 10.41s 10.50s launching at 2500 rpm with a 4.30 gear . this monster with a 4.88 gear and 4000 launch ran a 9.83 and I got booted off the track, heh, well done with a lot more potential,take care
