Hay mate, I've got the tapered bore pro race 50/48/45 itbs from EFI hardware $4,600 also had to get ECU,dizzy,injectors eg extra $3,900 this is just to give you an idea where you'll be heading if you decide to go in this direction.! Have I changed your mind? If your going to go for EFI you have to consider getting a new ECU that can run it! :-\ took me 12months to save for it, but if you can wait and do the same as i did it's worth it
