your favorite small block footbrake/bracket race torque converter
i know your car is strip only but my dad has a 451 demon that runs 10.60s in full street trim driving to and from the track with a 4500 stall dynamic. car cruises at 2900 rpm on the freeway. doesnt heat up and is super consistant at the track. he has had it for 5 yrs now and its been bullet proof. i have one in my car but have yet to run it.
