Hi,I have a stroked 351w (393) that is currently EFI and residing in my 87 that I am planning to drop into a 67 FB. The question is: Should I stay EFI or go to a carb? Clearly each has its advantages both in instalation/modification of the car/motor as well as end result. I really like the simplicity of the carb route but at the same time I have more experience with EFI... What are your thoughts? What would you do given the choice? Thanks

I like the "Old School" style, so carb is my vote. But like you said, they both have positives. Tough choice.------------------

Keep up with modern tech if you already own it and you are familiar enough with it for the swap to work. When I look at these high compression completely streetable new cars I get a little envious.

I think that I could make the swap work... Anyone on this board done this swap before? I wouldn't mind a reality check to make sure I am not overlooking any major components...------------------

I swapped Mustang SEFI onto the 5.0 Stang engine I have in my 1967 F100. I used a wiring harness from a junkyard T-Bird that had an "E" VIN code for the engine. It's also SEFI and I had to add the MAF wires into the harness. I couldn't see paying $500 for a bunch of wires when I can read a wiring diagram! Cost me $15 at U-Wrench-It! I used a Mustang A9L PCM. Works awesome!------------------

I?d like to see the results when you are done and here about any snags! I would imagine that it wouldn?t be any more difficult than an EFI 5.0 swap and I?ve read plenty about those.------------------

I'd go efi, more drivability,better idle,better economy,easier starting,lower emissions,more torque and depending on the system laptop tunability. I have a 67 must vert with a 351w, I ran a couple different holley projection systems, analog and digital and compared to a carb there was no comparison, the efi had better throttle response,fuel economy and made the cam idle smoother.I am building a 408 for my stang and plan on going port efi. this is the latest hot setup http://www.mass-floefi.com it will fit under stock hoods and use a maf stock ford style system. my 67 vert http://htwheelz.smugmug.com
