Stock intake modified to accept a Holly carb.

I took a rochester carb base to holly carb adapter plate, and tig welded it to the intake. The plate can be bought at any speed shop. You take the the rochester side (smaller side) and weld that to your intake.

I used a 500 cfm Holly carb jeted down to .62

I was just getting ready to tell you ask Monty, I was asking him about it a couple of months ago. Check out his site, it'a a nice rig.

The only draw back to that design is, what if you are sitting in the truck listening to the radio on a cold day with the engine off? You will be heating the choke coil and it will be difficult to crank. I used an oil pressure switch in series with the ignition to eliminate that problem.


Second note, I would rather have a holley than any other carb for off road. Not to mention that they are very adaptable to nearly any application (if you know how to tune it properly)

If you dont know how to tune a holley (and I dont mean just tweaking the screw adjustments) you will not enjoy that carb.

If your radio is wired to the ACC circuit and your choke is wired to the IGN circuit (as they should be) then if you want to listen to the radio the ignition switch should be in the ACC position which takes the IGN circuit off-line. The easiest and best method is to take the choke lead off the coil voltage before any voltage dropping resistors that may be in the circuit.



Me too, but most marine units are even better for off-road use - vented into the carb throat and some are designed to reduce the chance of leakage. I certainly agree that a Holley is nearly infinitely tunable - with many parts available.



True, but the 2bbl units are much simpler to adjust and tune than the 4bbl models. I've always maintained that the bad thing about a Holley carb is that you have to set it up correctly but the good thing is that you can - provided you take the time to understand it.

Is it a given that when switching to an aftermarket carb you lose the factory intake?

I'm not familiar with the 2.6L intake, but from posted comments I would assume that an adapter plate between the 2.6L intake and the carburetor could be made to work. It's commonly done on other engines to adapt a Holley to a Rochester or other mount. Here are some examples:

Adapters

Here's a Holley 2bbl/Weber single throat adapter - won't work on the 2.6L dual port intake, but just for an idea:

Holley/Weber

The staged dual throat carb is designed to provide better fuel metering and atomization at low rpms so some attention is needed when switching to a larger CFM 2bbl sychronous-opening carb like the Holley design in order to keep from having a low-speed bog. Good throttle response can usually be achieved, but may require a jetting change, accelerator pump and/or pump cam change and a power valve change to get it right.

When it comes to carburetors there's still nothing better for tuning them than a good seat-of-the-pants gauge, a good eye for reading plugs and a box of parts.
