I am thinking of converting from my Dominator to a fuel injection system for a 573 CI, 850 HP aluminium Bulldog block. Anyone converted a 455 block to injection and what system did you use?
I have the Retro Tek system which I beleive is similar to the new FAST system, but I have yet to install it. Its definatly a quality system, just won't be installed for a few more weeks sorry I can't give you better feedback yet.
I've been using the SpeedPro (subsequently renamed FAST) since 2001. I love it. The new XFI seems even better, especially with the traction control, but honestly I have no other need to change my controller since my car runs so fantastically. I have a lot of friends using FAST on their GNs, and they also love it. Occasionally I hear about someone who has a tough time with theirs, they don't seem to be able to tune it. Prior to that, I used the Holley Projection on my 455 since 1993, so I've been doing FI for quite a while... -Bob C.
