Fuel Injection
 
Vintage Motorsports now offers specific motors with EFI(427cid). What do you guys think of this? Does anyone have a fuel injected motor that they share their experience? Thanks in advance!

Efi is the way to go if it's a stand alone system. I don't like the self learning systems but others on here do. If it's a small block the self learning seems fine to a point. Big blocks with big cams sometime suffer.

I have a fast fuel injection installed on a 427. The o2 sensor was installed in the pipe per the location Backdraft provides. The engine ran rich all the time. I relocate the sensor to the header and now the engine runs as it should. I discussed this issue with fast fuel and 8 stack people. All I could find out is that the sensor is so far from the head it does not work. I did not have to reprogram the system. Just moved the sensor and the engine performed perfectly.

I just got off the phone with Brian in the service dept @ Vintage and they're still using the FiTech and its working fine. He did give me some valuable insight to the parameters and tables (FiTech gives you 5 pages of customization areas). I also asked if canned downloadable tunes would be a possibility in the future but since all the engines out in the world have so may built in variables that's not going to happen.
(I'm used to Mod motor world where they can email them to you)
I am also relieved the Super Victor intake I was pondering changing is not an issue as he's used that setup few times already with success. Their 427 typ run around 8" vac and it works fine. Mine had me worried since I am @ 9" at idle.

I think you'll gonna love it Zeke no matter which system you choose.

I have a 2014 Backdraft R3 with a Roush 427R. I had no problem with Arizona inspection and registration with the aspirated carburetor. My registration is $30.00 per year as a vintage vehicle. The inspector told me that a Cobra (new or not) that is not equipped with carburetors will not qualify for vintage registration. Regular registration in Arizona is subject to registration costs based on the price of the vehicle and would certainly exceed $500.00 per year. Hefty price to pay for FI and maybe more when the insurance bill rolls in. Might be the inspector was incorrect or it might be that Arizona registration is unique with this constraint. Phil.

Wrong. My spf was efi and I had historical plates registered as a 1965.
