I've got 5 different converters, Coan, Trans Specialties and 3 Turbo Action... I had the best results with my T/A... these are all for a 727 and I am putting a T/A in my Rampage with a 518 trans... I am hoping it flashes between 4500 and 4800... I do have another T/A conv around somewhere and it flashed at 3500 but that was in a screwed up engine with no torque so I might give that a try behind the 416 with considerably more torque so it would be a higher stall... the Coan sucked so I bought a trans specialty conv and that was a bit to loose for my engine at the time but it might work well behind my W-9... currently I have a T/A in the race car that stalls at 5600 and I am hoping that the trans specialty stalls about 6100
