When a converter company advertises a converter to be a (lets say) 3000 stall speed, is that footbrake stall or flash stall.How close to the advertised stall has the converter actually footbraked to on ones that any of you have bought?I have a maybe 400 horse small block in 77 camaro with a th350 and what was supposed to be a 3000 stall.It only footbrakes to 2300 maybe a little more.But this thing is slow off the line,1.85 60' with an 8.12 @ 87 mph in the 1/8th.No tire spin just slow.I need atleast a 1.6 60' to get this car to run what it should,but I dont want to go to high on the stall and have it slip all the way down the track.I need one that will footbrake to 3500 or a little higher but still grab good.Any ideas?THANKS.

Stall speed listings are based on an engine producing
230 lb. ft. of torque @ 2,500 rpm. More torque @ 2,500
rpm will give you more stall speed, less torque @ 2,500
rpm will give you less stall speed than the stall speed
ratings indicated.
