I used the 750 Eddie on my 73 Dodge truck 400 BB. Seems to work better than the thermoquad. Been working for 5 years now but could use a rebuild. I agree with everyone on getting the 800 Eddie for your 440. With juice it should be a little wild. What car is this in? Any 1/4 times yet?
Snap your neck, mega G-force launch, is all I want!
