I have a stock 225 in a heavy car (66 Fury I) I'd like to go to an EFI setup but I'm not into JY kitbashing. In the opinion of the board would I be better off using a three weber dcoe type setup, or get a clifford 4 brl with bungs machined for injectors?

I don't want to race, just focus on carefree reliable cruising.

What are your thoughts?

Do multiport (indivdual injectors per each hole). You will save some money if you do throttle body type injection but its pretty minimal compared to overall cost so you may as well go all the way. Thats the way I look at it. Plus multiport leads to a smidg more power and better fuel distribution

Clifford = hassles, whether you're buying their halfbaked EFI setup or their halfbaked headers. If you're determined to install EFI, definitely do the relatively minimal extra work to make it a port injection setup rather than throttle body injection. Don't want to cook up the parts yourself? No big deal, you can get most of what you need prefabricated—just expect to pay for it. Not an electronics whiz and don't want to cobble up the software yourself? No problem, go get a ready-to-run controller with integrated tuning interface from www.sdsefi.com .

Too many people who were born on third base actually believe they've hit a triple.

When I priced out tripple Weber carbs and manifold versus multipoint fuel injection, it actually came out very close (besides the support gear for fuel injection: electric fuel pump, fuel rail, regulator, etc.)

Full boogie carb setup:

Brand new 3x Weber DCOE + manifold lines and linkage: quoted about $1800. Then you need to figure in tuning parts (x6 for the 3 carbs).


Full boogie aftermarket EFI with little DIY:

SDSEFI fuel injection computer and harness for injectors*: EM-4 6F- $1485

Modification of manifold for fuel rail and fuel rail: anywhere from $200 (local shop) to about $475 (quoted by Rance Baxter at Rancefi.com back in February.

Junkyard throttle body (Ford 4.6 Mustang, etc.): $20

Electric fuel pump: ~ $100 (http://www.autoperformanceengineering.com/)

Injectors: prices vary widely, used or new. Figure $150

So, you can see that carbs or FI can add up to be roughly the same price, depending where you shop. Of course, fitting an old car with carbs is MUCH easier...no extra wiring, fuel pump modificaitons, etc.

*The www.sdsefi.com Racetech unit includes parts for a crank triggered distributor-less ignition system complete with coil packs (and complete control of the timing curve).

And fyi - even the all in one box kits are not bolt in, they are generic. I highly recommend against a one size fits all harness because you'll still have to modify it to fit right.

You don't have to go to a junkyard. Personal opinion? Get the manifold/rail/holdown made at one of the shops mentioned above. They also sell the other items, injectors etc, but if you want variety or better pricing you can try www.apeusa.com for pumps, www.fiveomotorsport.com for the injectors, and megasquirt from www.diyautotune.com

I tried one of the all in one kits from howell and it isn't something I will ever do again or recommend to someone else. All in ones are good for chevy, jeep, etc that they are based off of. If you had a v8 in the fury edelbrock and others make an all in one box kit that will actually fit. But for a /6? Nope.

Actually Patrick I am comparing two different types of EFI setup available. One is based on the Weber Carb but is essentially an individual runner TB injection setup similar to Tom Drakes system and the other is based on a more conventional intake with bungs right at the head and a single TB similar to the Hotrod EFI slant buildup comissioned by Romeo Furio (I think). Both setups are shown on the Clifford webpage even though the pic of the Mopar Webber type setup is not a slant (in the picture that is)

Oh, OK Middy. I reread and I understand beter now. There are advantages to individual runner setups (having to do with eliminating the interaction of pressure waves in a shared plenum manifold), and more tuning can be done with different length air horns, etc. From what I've seen, those individual runner type kits (like this one http://www.racetep.com/weberfi.html ) put the fuel injectors farther from the intake ports/intake valves than a manifold modified for multipoint injection. I really don't know how much of a difference this makes, but it's something to consider.

The farther the injectors are from the valves makes a more uniform mixture and greater max power, closer to the valves means a better idle and less emissions.

Individual TB's also requires them to be syncronized. A single TB means an easier setup.

As in everything, there are trade offs.
