Hmmm,
That says that the 550 and 1600 injectors are good for over 650 HP!!
The "V" in Velocity must stand for Vertical take off! :>)

Chris,
There was a lot of traffic on this subject in 2003. IIRC Ed Anderson
was/is using MSD injectors (2012?). Dunno if they will fit the Mistral
manifold, though.
Some interesting info here:

HTH,
